Replacement Exercise?

Replacing back squats w/ bulgarian split squats?

would doing this be okay? would it be okay if my lower-body training consists of deadlifts and bulgarian split squats?

well…it would probably be best to rotate among all the diff squats over time, as in bulg splits, back, hack, front etc.
what is the reason that you want to do away with the back squats?
it would also be good to rotate the various deadlifts also.
