I kinda wish we could get Super7 Ultimates styled blank bodies.

 Note that I said Super7 Ultimates styled bodies and not Super7 giving us blank bodies... because they'd be like $75 each and having to wait 12+ months is a drag. By the time the figures get here, I'd probably forgotten what I wanted to do. 

I know that most folks would say that double jointed articulation on figures is better. I agree 99.87% of the time, but for the sake of this "theoretical line" I'm going with the option of single jointed, since we're going to have to paint. Less parts to sand. Also let me specify something... technically speaking these shouldn't be action figures, they should be articulated model kits. 

Let's  say 3 male body shapes, 3 female body shapes:

Slim, buff, Roided for the men. For the women we have slim, toned, and Amazon. (Amazon is not only buff, but taller.) Each female character would come with different breast pieces in case you want: petite, medium, large, or "how the hell does she sleep with those things!?"

Obese models would come later.

Now for each body type you'd get three options:

Naked

Tights

Baggy clothes

Naked as the name suggest is a naked figure. (Yes they'd be anatomically correct.)

Tights would reuse the arms and legs of the naked body, but instead of naked feet, you get sock feet. A Mickey Mouse crotch wih no details and the torso loses some muscle definition to simulate Spandex.

The Baggy clothes has some optional pieces That can be used.

For example the upper torso has a plug in hole where you can add

T-shirt neck

Turtleneck

V-neck

V-neck with tie youalso get jacket or suit overlay as well as matching sleeves.

Wifebeater top (sleeveless tanktop. For muscle shirts just use the T-shirt top with bare sleeves.)

Additional parts could be sold separately. Not to mention "generic figures " like say Policeman, gang banger, etc.

You could mix and match parts and if you have rudimentary sculpting skills, you could combine body parts and make more figures out of the spare parts. The old Shapeways Custom Andra review was what gave me the idea. The reason I chose Model kits was because theoretically speaking they'd be cheaper than Shapeways or the action figure version of pick-a-brick. 

Now these kits, while Customizable, due to having compatible parts, aren't completely modular. As some parts would have to be glued for assembly. If you want to have a deformed character, you could mix and match certain pieces but only from a class above or below... for example, Buff can use both Slim and Roided parts. Like say, you want to make Fappening dude

You use the Buff clothed body with t-shirt neckpiece. The jacket overlay would require some cutting to fit the Roided right shoulder piece. For the left side, you use the slim arm.

Or if you'd rather have a "realistic version of Final Fantasy VII game model" type character:

Like This but not blocky.

You start with the buff clothed body. Turtleneck attachment for upper torso

Slim Lower torso clothed

Buff crotch

Roided clothed pants

Buff clothed lower legs

Roided boots

Roided  naked or spandex shoulders

Buff naked or spandex arms

Roided forearms and hands.

Why would anybody do that? Aside from a visual aid for part compatibility purposes? I dunno but the possibility is there.

This gives me an idea for future expansions like Malformations (4 armed torsos, mid animal mutation, multi-headed bodies, monstrous faces, etc.) 

Logistics is the only thing stopping this dream
