I have an idea

I have an idea, and I need to know if this has been done before.  I want to have a 3 laser flashlight host.  One green, one red, and one blu-ray.  I know that I will have to disapate heat, so I need to find a small, but large flashlight that will be able to host this 3x laser.

My next problem would be to find a switch that will alow me to power one laser at a time and then all of them, if I wanted to.

Has anyone tried to do this yet, and if so, do you have any tips for me?  Thanks a ton.

Also, if any of this doesn't make any since, let me know and I will try to explain it.

Look for member "mausweisel", or something like that. I probably misspelled it, but he had a mod with all 3 side-by-side in an MXDL host.

Also, Rog's project has all 3 colors coming our of 1 objective using beam-combining optics, it's popular around here as well.
