Looking for the most crazy RGB keyboard (full) or how to mod mine to get there.

I have a K100 Pro and would love more RGB cause the rest of my RGB is MEGA over the top, all controlled with SignalRGB.
Fromm research it seems POM Jelly caps are a great option but finding ones with legend is proving difficult.
Any suggestions on options for my K100 Pro or if need be, an different keyboard?
Thanks
