Hm, are the PPUs compatible? Could you rip one out of a PAL NES, put it in an NTSC one and have a 50hz NTSC system? If so it shouldn't be especially hard to put both in at once, with a switch on the power pins to select one; you wouldn't be able to switch in-game but it'd still be convenient.

you can exchange ppus, yes.
its even possible to exchange ppus with an arcade system, thus having a nes with true rgb output.(the french nes doesnt count)

its not possible to switch them via their power pins, no.
it could be possible to switch between 2 ppus by using their clock pins.
i havent tried that, though.

the biggest problem is just the clockspeed, be it on SNES or NES and the Cartridge sizes (NES <-> Famicom, US SNES <-> PAL & SFamicom)

For NES, there exist tutorials on the net to install a 50Hz / 60Hz switch.

the other problem is additional hardware in the carts themselves, Super Mario Bros. 3 uses a additional MMC chip, also do all games over 32KB. (On Game Boy also).

SNES also has various extra chips, the most famous being the SFX Chip in Star Fox and Yoshi's Island.

i think you are talking about the lockout chip disable mod.
that one has nothing to do with video modes.

you'll have to find an appropriate donor cart if you want to build a cart yourself, thats right.
however, its not that hard to do super fx or dsp carts.
sdd1,sa1 and spc7110 carts are lots of work, and donor carts arent always readily available.
its not impossible, though.
