 If you install a GT3 master cylinder and use a bleeder system that PUSHES the fluid from the bleeder back to the reservoir do you think that you may get away with a proper bleeding without activating the ABS/PSM pump?
 
 Your comments are always appreciated.

I have no idea as I dislike and do not use bleeders that function that way because they push the most contaminated fluid (near the caliper) backwards into the most sensitive components (ABS/PSM/master cylinder).  I think Porsche may have released a technical bulletin suggesting against backward flushes.
Just out of curiosity, why are you using a GT 3 master?
