You could generate your own ...

Have you contacted Loren Blaney yet? I think it's trivial to do that through the 6502 Group website http://www.6502group.org/ . That site was set up long after I no longer was an "active" in the group. I'm not expert regarding XPL0, or 'C' for that matter, because I prefer to use ASM for small jobs under, say 500 k lines, and I attempt to get others to do the big ones.

I doubt that it will be difficult getting source code for everything. The compiler, BTW, is written in XPL0. Since the evolution of the PC, the intermediate language interpreter has more or less fallen away, but it's a construct you might find useful. For the 6502, it was about 2 KB, and the compiler was about 8 KB in memory. Since you may, based on history, have some understanding of the significance of those figures, you can evaluate whether you'd want to do something similar. You don't necessarily have to use XPL0 as your source language, nor do you have to use the I2L architecture. However, as a concept, it's a sound and thoroughly proven one.

You don't have to reverse-engineer anything, since commented source code is available. There's even a manual.
