eblade frame should bolt right up as it uses the same holes as any other cocker frame.
ego frames do not mount similarly. their front screw is in front of the trigger guard whereas cocker frams the screw is placed further back inside the trigger guard. theres a DIY sticky in the voided warranty section on ego framing a cocker...i think you can put the rear grip frame screw into the one that was holding the ivg set screw....might be a problem if yours doesnt have a threaded ivg. other than drilling a new hole in the frame theres really not much else to it.
i have no idea about angel frames.
shocker frames are VERY close to cocker mounting holes.
only real issue i think youll encounter is the pre-2k's having a smaller valve chamber which may cause issues for the mq2 at lower pressures and higher rof's.
also if you change to an eblade and still use the mechanical valve i think you will need to change the hammer lug from a rounded to a flat one...i may have that backwards though.
