Want to make to sell: Onehanded controlers for Older Systems

[nightwheel]

Yes one again I'm wanting to make things to sell. This time around it's one handed controllers. But I will only make onehanded controllers the listed systems. If it says Possibly. That means: I might make one, But its acording to how complex the controller is inside. The list:
SNES
Sega Genesis
NES
Sega Master System
Saturn (Possibly)
Jaguar (Possibly)
2600
5200
Odyssey (possibly)
Ddyssey 2 (possibly)
7800 (possibly)
Sega SG-1000
ColecoVision
TurboGrafx-16
Neo Geo (possibly)
ColecoVision (possibly)

And if anyone is willing. I have a idea for a Wii-Mote Mod. Putting a Wii mote in a N64 controler. And still have it where you can still use it to point and click stuff on the wii. And Buliding the Nunchuk into the controller. It would be great to use to play some VC games or play Shooters with.

Sorry but, all those are uncommon systems. It is nice that you are thinking of helping out disabled people though.

Not sure if it's possible, but it seems like it might be.
Couldn't you just rewire a Wii Nuhchuck to perform as an awesome NES controller? You would have to add to buttons, "Select" and "Start", but that would only take two tact switches. Not sure if you like my idea, but I think it sounds cool. If I get a hold on some Nunchucks, I'll try it!

P.s. I love your idea!

...EDIT...

Just realized the button placement would be awkward to play with, seeing as you need to hold both A and B at some points in certain games, so you could possible rewire the trigger as B, the button above that as Start, and add a Select and A.

Im switching gears for a minute. Does anyone have a damaged Wii-Mote and Numchuk that works. Plus a N64 controler shell with buttons. That their willing to trade for Genesis and a few other things if nessary? Im going to try to make my mod idea. Free would be best, but i doubt any of you would do that. You will get some credit when i finish my mod .
