I knew about the odd numbers being used in forest plantings, but I wasn't aware the same concept was used for branches. Now that I looked at it again, that was one of the things bugging me, was how it looked a bit contrived with 4 branches sticking out from each corner. I am definately planning on growing more out so it wouldn't be obvious in the future, but I'll need to think of some solution.
As for the tree recovering, it's been in the 70's around my area during the day recently, so I've been putting it outside when I leave for work, and taking it back in when I get home. The house is plenty warm for it, so I just have him sitting near a big sliding door where he can get as much sun as can make it's way through the glass. Quick question, would a normal humidifier pointing towards my tropicals keep the humidity up around them without causing any problems? I was trying to think of a somewhat easy solution to keep the humidity up, without resorting to massive plastic bags around everything.
As for style, I was looking towards Banyan style. I haven't seen many good Banyan style Ficus, so I'm wondering if it's a difficult thing to do. I'm simply looking at the pictures of Banyan's and doing my best to move from them. I was wiring the branches to move horizontally away from the tree, and then in the future I could encourage aerial roots to form from those branches, heading down into my hypothetical Bonsai pot.
This is the best example I could find.. though slightly larger than I think I will be able to create anytime soon:

Thanks for all the suggestions and such.
