optics options

alright so i am attempting a new approach to wavelength combination. my design calls for RGV at 120 degrees in the same direction and reflecting 180 degrees into a center point of the three beams. the two ideas i had where one, having a custom prism made from who knows where, in which the beams bend and reflect off the same point in the middle back down, if a shape is possible for that(which is my first question) or reflecting the beams into the center and using a rod mirrored on the sides to force the wavelengths together and re focusing the light.

would having all three beams polarized at the same time cause them to combine and give me some crazy wavelength?

Best thing that would happen is you get white out - not some crazy color.

But I think that's an interesting idea - essentially, just using orthogonal lines to an equilateral triangle, right?

well kinda. the center, combined beam would be parallel to the individual color beams, just going different directions. im just not sure how far the beams would go still being combined.
