You'd also need to avoid generating harmonics above fs/2 to prevent
aliasing, unless that's part of the "personality" you're going for.

Wrong. An analogue amplifier with lots of negative feedback, eg. a
typical op amp or power amp, will usually hard clip.

Yes, although clipping threshold can be any level you like (within
reason) in floating point.

That depends on whether you want to modify the frequency response
before or after the clipping harmonics are added. Both can be valid
