Like the title says, can anyone mod these?

I haven't seen a thread on anyone modding these. I just got both, and would like some more efficient LED's, as well as drivers, and maybe even neutral emitters.

The TLR-1 looks like it's an XPG/XPE LED mounted on a driver.

The TLR-3 has an XRE, but I'm not sure how to take it apart.
