That combination has a lot of merit. Depending on how much time OP had to go looking, he might even find a used FA50/1.4 at the right price, which would give him a truly fast and nicely spaced prime combination.
If he's in a hurry, though, I'm pretty sure he could score both the 35mm and 50mm plastic fantastics for under his maximum new-in-box (if he wanted the warranty protection), and he would not be doing badly at all. That's a good fallback position for him if time is short (ETA or if all the options we're presenting become too much to think about, LOL!!).
