I think your best bet would probably to go with DLED36s since they come stock with the 39 degree beam angle. You can also get roughly 2 for the price of one DLED108.
Have you looked at the Opti RGB with lens kit? This might be an option since it is cheaper then the DLED36s, with the lens kit.
Here is another idea, look at the Opti 30 RGB. You should be able to get between 10-15 at that price range. You can use those 10-15 Opti 30s to replace the DLED36s for your back drop wash and move the DLEDs up front for front wash. The Opti 30 RGBs won't be nearly as punchy as a DLED36 and have a smaller beam size, but the bang for the buck is great on these things.
I have some shots of a DLED36 vs a Opti 30 RGB if you would like me to post them so you can get an idea.
