Already featured in
The Trophy Case, the characters I hope to feature someday in
Trophy Case Comics will be Major Magus, Spyhunter, Prince Inaros. They would later be joined by Rocket Ranger, Mr. Crimson, Minuteman (the only non-pastiche ringer), Captain Magus, and Lady Magus.
I just realized-Fawcett actually has a Minute-man:
Also, it would be nice to see a Kid Eternity mock-up, but i'm hornswoggled if I know how to model him-Summon any dead figure as a temporary SCM, go intangible and invisible at will for as long as he wants, overwhelmed in combat by four to five low HD Mobsters at once......hmmmm, High Level Ghost Specialist Magic-User? Limited to Summon Mobster as the only spell, but can cast 2 Levels higher (1 Mobster at Lvl 1)? His SCM is his Magic Wand (can't cast without Mr Keeper in earshot)?
Frack it, we're going to need a special Class aren't we?
So Be It. 
The Summoner: A highly specialized form of Magic User, using the MU advancement table, attack capability, and limitations on weapons and armor. The Summoner may be able to figure out Scrolls and cast them, and use other M-U magic items, but have no spells of their own and cannot gain any, ever-also they cannot enter psychic combat as a normal M-U (nor be forced into it). Instead, the Summoner has either been imbued with otherworldly power or tamed an otherworldly force to do their bidding. This connection nets them the following:
1) Summoning. The Summoner can call to their aid Mobsters of up to Lvl HD per day-they appear out a ring of fire, glowing door, puff of smoke, claws out of the earth etc.. The Summoner must name the type of Summoned creatures at character creation (Historical Figures, Imps of Darkness, The Undead, Newsboy Armies, Mist Demons etc). The Editor and Writer determine together what abilities these creatures have (Historical Figures have the skills they were famous for, Imps of Darkness see in the dark and have claws, Newsboys have access to writing instruments, cameras and or bags of newspaper, Mist Demons cannot be harmed but cannot harm in turn, only Grapple and Blind, etc). The Summoned beings can remain for one full exploration turn(or a full combat scene) and then vanish.
2)Affinity. If the Summoner happens to meet any Mobsters of the type they Summon, they will be able to communicate with them automatically and may attempt to recruit them as temporary SCMs (Reaction Roll as Usual).
3) Related Magics/Powers. Any magics keyed to the Summoned Mobster type might be available to the Summoner as a Spell or Power(Read Languages and Magic for Historical Figures, Find Evidence for Newsboys, Fog Cloud for Mist Demons, Light[Reversed] for Imps of Darkness, Spook Bad Guys for Undead etc). The Summoner gets one ability at Lvl 1 and another at Lvl 5, and the Summoner's Lvl is used to determine range, duration and effect. Unlike most M-U's, the Summoner sacrifices 'Summoning Ability' equal to the Lvl of Spell or Power to make them work, reducing the ability to Summon per day.
(Essentially the Summoner has Spell Points=Lvl. Spell Points Summon Mobsters at 1pt/HD, or fuel Ability as per Lvl of Power or Spell-Invisibility=2 Spell Points).
4) Focus. All Summoners have a Focus, whether a wand, staff or piece of jewelry, or a free-willed SCM (living puppet, animal or demonic familiar, spirit guide etc). As long as the Summoner is within 30' of the focus their Summoning Ability has +2 HD...but out of range their power is at -3HD, possibly leaving lower Lvl Summoners powerless. A Focus that is destroyed may be renewed or reappear in 1D3+1 days.
Examples:
Kid Eternity-Lvl 10 Ghost Summoner(no name in the Fawcett version).
Ghost Powers-turn insubstantial 10 Turns per day
Theme-Historical (and sometimes Mythical) figures
Bonus Abilities-Read Languages and Magic, Invisibility
Focus-Mr Keeper, ghostly guardian
The Shade (James Robinson version, early career) Richard Swift, Lvl 4 Half-Human Summoner
Half-Human Abilities-See in Darkness 30', Hide in Shadows +1 ,'Animal' features-eerie unnatural eyes, sinister body language, shadow sometimes out of synch
Theme-Demons of Darkness
Bonus Abilities-Darkness (and after Lvl 5 is reached, Spook Good Guy)
Focus-Ebony Walking stick
.....Oh Carp, I just hijacked another thread didn't I ?
Sorry. I should have just said 'Make Kid Eternity a High HD Lawful Mobster and assign powers as needed by the Editor, nut NOOOOoooo, I have to do things the Hard Way...
Just to get back on subject-are you planning on doing any Villain Pastiches as well?
("Sir, you're not gonna believe this, but the Hijacker has released the passengers and parachuted out of the plane! We're headed home!")
