I want some lights above my cab, but my truck is mainly a DD so I want to make the whole rack removable

I was thinking of making something that sits in the tie-down holes in the bed of my truck, that possibly bolts on somewhere, where i can mount 4-5 HIDs (probably 9" to match the lights on my prerunner bumper)

I just mainly want something that can be taken off, without having to drill into my truck anywhere or anything

IDEAS PLEASE
