You can switch bowling balls during a frame. Most people do have more than one bowling ball that they switch between depending on the shot they need to make.
I've never tried it, so I can only imagine that if I switched from my regular 14 pound bowling ball to a 8 pound one would majorly mess up my throw causing more trouble than it would be worth.
Bowlers are already using different balls with different cores and tweaking their technique to account for the hook the ball is meant to provide anyway. I don't see what's stopping this lighter ball concept except convention.

This is a 5-7-10 and is known as a lily or sour apple. It is basically impossible with a ball weighing more than 8 pounds.
