Nice idea but the wiring will have to withstand constant stuffing and folding.
An external locator is really useful on dark nights, I use my windup radio LED unit.
Most LED lighting is very directional, like a headtorch. It would be nice to have some diffuse ambient mood lighting, maybe something between the fly and inner. A red/green/blue LED set could be set to your fav colour.
My Hilleberg tent has typical Swedish interior design where they though very carefully about the colour of light.
