OK, after reading a bit more, I have decided. It IS possible to do what I want, but the cost of just the FETs would be well over what I consider "inexpensive". As such, I will just get a bunch of bipolar transistors (TIP33 looks like a good candidate) and design in some emitter resistor compensation. At BGMicro, I can get all the parts needed (minus what I already have) for TWO high-amperage supplies for well under $100.
