First off - I have all kinds of acrylic so just drop by and I'll give you some.
Second - I agree with Chuck as for using zip ties.
Third - I'm only asking you these question so others that are interested in doing this know the reasons to do it. I guess what I'm saying is don't get pissed because I'm asking questions.
Forth - If you do this mod could you take photos and put it together as a DIY for everyone? It would be awesome if you could

Why do you think you need this on your skimmer?
What do you expect to get out of the mod?
If you really want proof it helped, I’d get an air and watt meter to see what you have now. After the mod test again to see if either of the above improves. You might be able to borrow someone's. I'm thinking about getting a watt meter and a air meter could also come in handy . . . might have to look at prices.
