Has anyone built a Plymer 80 Frame with a Glock 19 upper?

I have always wanted a "commander" like glock.  A 19 top-end on a full size lower.  Everything I have read says you can't do it?  Why?  If all the parts are interchangeable, can't you just cut the end of the "frame" to match with the 19 slide profile?  Maybe a polymer 80 frame would be the way to go.  Just thinking out loud here.

I've seen people cut the grip for a shorter grip with full barrel. 

I haven't pulled a glock apart in a bit but there are inlays at certain junctions. I'm not sure if you  would be cutting the inlay. If I wanted to try it I may be tempted to pick up one of the drilled and assembled glock lowers that are floating around and do it that way instead of having to drill it.
