I think it would depend most on why his cholesterol is high. If its because of diet yes it will reduce. If its because of genetics it might not. Excersise is the only thing besides medication that will help with genetic high cholesterol according to my doctor.

We had a long talk about cholesterol one day because she had to increase my lipitor from 20mg to 40 despite the fact that have been conciously on a low cholesterol diet of sorts for the last 10+ years. I started to get really upset. Cause we do eat very little fatty foods. She said mine must be more due to genetics then diet and that was why she had to increase my dose.

But heck losing weight and getting more excersie will help with all of his health matters in some form, so even if it doesn't handle/reduce the cholesterol he still has other good reasons to do somekind of WLS.
I can't blame him for not wanting a bypass the fact they cut up and rearrage internal organs turned me off of it too. lol
plus everyone I know personally whos had the bypass have nasty side effects or are gaining their weight back!!
