I suggest you give Mark Housel a call and explain what you have in mind. He has great expertise in milling slides and RMR installations. He might be able to tell you if you're barking up the wrong tree with this project.

Regarding aftermarket vendor support to produce a G36 slide, the answer is quite simple. The G36 market is minuscule compared to the rest of Glock's product line and no vendor wants to absorb the development and overhead costs for so little return. In the Glock 45ACP line, the demand for custom, aftermarket offerings drops off precipitously beyond the G21.
