What's the feasiblity/practicality of drilling a cast iron bathtub to retrofit whirlpool hydro-massage components?

It's hard to drill cast iron. But it can be done. They do make bits for that but it's going to be a very hard job for someone.
I would beg off on it.

Adding holes means probably cracking of the glaze. That leads to rust. I'd be very leary about making holes for those reasons.

If you were here, I would refer you to the company which does it. IT is seldom a DIY project.
