The problem with that is with the reel up the butt,your left hand will be on the end of the reducer(butt end)as it now becomes part of the usable butt section during the cast.Your right hand holding the reel being the pivotal point in the turn over of the rod during the cast, then punch,right hand, pull left hand.If the butt end is not specifically strengthened,it may crack the bottom of the actual butt section.
Zziplex and Century are strengthened specifically in that area as far as l know,so you may okay with one of their rod blanks.
I would knock the stuck reduccer out solve the problem.Stick length of dowel rod down the inside of the butt from the joint/spigot end.Few taps with hammer on dowel end it ll pop the reducer out it works.
