90-98 CR125 cases with 89 heads?

Hey guys just curious if this is a doable thing. I have an 89 head with a 144 kit/race porting and I'd like to rebuid the bottom end but new cranks are only available for the newer cr bottom ends. I would like to put he 89 top end on a 90+ bottom end. Any thoughts?
