Sorry Konrad, but I reckon this is a dedicated hardware job, with drive values loaded perhaps by an 8052. You are asking far too high a bandwidth to be realistic I think. Better to suborn the switching task to your own hardware, with phase offsets loaded by your micro, possibly clocked by the micro. Use a pair of ROMS as lookup tables, and a state machine to read the values into mutitiple 32 bit down counters.

2Khz seems too low for a switching converter or am I missing something ?

I fail to see why you need 1 part in 3,600,000 angular resolution. Why ?
