I have 2 XT Shadow+ Rear Derailleurs, both cages are bent. One is completely demolished and the other is mild/moderately bent (still rideable but not ideal). They're both very new so am reluctant to drop the money to buy new derailleurs outright. I ordered through my LBS replacement cage assemblies ~3-4 weeks ago and not looking too good.

Question is are the GS cages the same across most-of/entire range? Considering buying a cheaper Deore/SLX/whatever derailleur and transplanting the GS cage to my XTs. Would this work?
