I can't speak to the Gen 1, but I know the Gen 2s (6G74) can use alternators from the 2003-2006 Hyundai Santa Fe 3.5L since it's basically the same engine and those alternators are 120 amps vs the "stock" 85 amps.

Regarding Bumpers maybe making adapters so that you can use commonly available bumpers from other vehicles like Cherokees or similar sized vehicles would be a good offering, for both front and rear.

If I get my '94 SR running again I'd be looking for bumpers, winch mounting, dual-battery mount and some roof rack options.
