Blackhawk Gladius Maximis mod?

Hi, I did a lot of research about modding my outdated gladius maximis.
It's an updated version of the gladius night-ops I think.

I read every article I could find on the gladius night-ops flashlight on this forum.

It will be my first flashlight mod and everything is very new to me.

What I want to do is put a CREE XM-L in with an optic instead of a reflector.

I narrowed it down to these products:

CREE XM-L T6 on a star: http://www.led-tech.de/en/High-Powe...rie/CREE-XM-L-T6-on-Star-LT-1734_120_170.html

CREE Power Optic 10°: http://www.led-tech.de/en/High-Powe...°--usable-with-diffusors--LT-971_106_115.html

I think I need a lens holder, what I want to use is a CREE lense holder.

CREE Lense holder: http://www.led-tech.de/en/High-Power-Supply/CREE-Optics/CREE-Lense-Holder-LT-975_106_115.html

I will need some thermal compound to put these parts together.
I might mix theses two products: Heat conductive glue and heat conductive pad.

What I want to know, is this a working combo? Are theses parts compatible?

Let me know what you think of this setup, and I welcome every inputs and tips you got for me.

Thanks a lot!
