My experience with a full frame sensor (KAI-11000M) on a RC10 wasn't that great (bad vignetting and field curvature) but if you got good results with a DSLR then hopefully you're OK...

The 3nm narrowband filters are particularly spendy but worth considering for Oiii. Helps a lot with light pollution and also provides some moon tolerance.

Large sensors are just less tolerant of any small amount of tilt wrt the image plane.

If you're used to 30 minute subs then you should be fine.

Dark current noise is rarely a major issue with CCD cameras. Read noise is the real enemy and the impact increases with the square of the RN. With low read noise you can do much shorter subs, hence shallower wells aren't a real problem.

That's an image scale of 0.46 arcsec/pixel. If you had great seeing and an AO unit it might be worth trying but for typical SE Qld seeing you'd be significantly oversampled.
