I wrote a response but I think the mail got lost :-( so I'll try again.

yes. It is not a trivial task but should be manageable.
(some modules require special care like filters that mantain state information
etc).

Basically when a MIDI event occurs the MIDI Keymap module picks the right
sample (key and velocity mapping) and sends pointer to sample data and 
sample length to the sample module.
Same must be done for looping etc.
As for modulators I was thinking using events that send (base, increment)
values. That way you can approximate complex curves via small linear segment
while still having a fast engine.

>And is pitch really pitch, or is it rate.

Sorry yes I think it is rate. Basically rate = 1.0 plays the sample at
normal speed. rate = 2.0 double speed (one octave up etc).

no problem, I'm in the same situation so I'm the first that has to shut up !
