1. It's closed source, so that throws that out the window
2. The code is very likely to be non-portable considering the amount of effort required to get it running on Win/FreeBSD/Linux, and since the Win32 code is so different (d3d backend), it may as well be a completely separate project
3. Even if the developer opened up the source code, it would take so much effort to integrate it with mesa/DRI/DRM that it'd be easier to rewrite it from scratch
4. The renderer seems to sacrifice accuracy/precision in the name of speed, and that's generally not how mesa rolls (at least not without making it a user-tunable option).
This is just more of the crazy Germans and their ray-tracing, software-rendering nonsense...
Does a chip even exist in the sub-$10,000 range which could draw a game like Mass Effect 3 at 60 fps at 1920x1080 in real-time using ray tracing, software rendering, or both? (We're assuming just the actual visual fidelity of a game like that, not THE actual game, because you'll say that the API it was coded in is fundamentally flawed blah blah).
Don't google it; I'll answer your question: No.
