Thoughts: Taking B-body axles to A-body length

Good day,
Just seeing If anyone had any experience with taking B-body 29 3/16 length axles down to A-body 27 3/4 length. The axles are Moser 35 spline. I realize the axles would probably need to be re-splined and hardened but just not sure if it's worth it or if it's possible to just cut them down 1 7/16 & be ok. Axle spline length is 3". A spool would be used Street/strip 618 Hp small block.
