from your post I have concluded that you are a very knowledgeable and capable individual with style beyond the rain gutter solution. It is very easy to make a metal hood to hold any lighting system.
All you need is a piece of metal thinner than 30 gauge, a pair of red metal snips , pop rivet’s and up here in NY they are called flanging pliers down south they are called tongs .
If you provide the numbers I would be willing to lay-out a pattern for you.
Only caution with plexi is it will warp if it gets too hot. Funny you mention Fox as I just bought a filter from her very recently that needed some coaxing.
Theres a way to make some pretty slick sliding glass tops too using plastic trim thats usually in the flooring section at stores. I actually like them more then the typical hinged tops, kinda amazed no one makes them specifically for tanks. Works best with glass which some stores sell and cut pretty cheap.
