Locked into OSC (you could swap one filter at a time with a mono, but then run the risk of dropping a filter onto the primary, in the dark)

No OAG, which means a guide scope for guiding and probable flexure issues

Personally I think you back yourself into a corner doing this method (converting a newt).

Well yeah, i guess that all makes sense given the size of a cam and filterwheel, it is a fairly pointless activity.
