Suggestions for hood? Since I broke mine!!!

Any suggestions for a 20L hood? I have a hob which was a perfect fit for the cutout section of the Aqueon deluxe full hood (ha, deluxe...)
And it had the single glass pane in the center for the light to sit on... But I got myself a hydor slim skim nano, and it was JUST alittle bit bigger than what I had cut, and when I went to cut the hood more, I freakin broke the glass.... lol
I'm not entirely sure it would have fit anyways, I didn't have a tape measure but I'm sure it would have needed 1/8-1/4" more space for the hood to fit on with it there...
Anyways, I need a hood for a 20L, I was contemplating the generic glass covers, but if I recall they only fold in half across the tank, whereas I need something that can be cut, or I would only have half the top covered, and have to Macguyver something to cover the rest since the hob is a little smaller than the depth of the skimmer, and I don't think I've seen any hoods that would cover 2/3 of the tank from front to back...
I'm thinking eggcrate+plexiglass might be my only solution...
Suggestions?

 

Ya, that's the thing that sucks, it's 12-12.5, and the SSN is 3x3.33"... lol :/ So I believe I only have about 9.5" give or take to work with... too bad there's not a modular cover that's made with multiple 3" glass sections.. spose that would create some non-clear areas the lights would have to deal with buuuut...
