You sure can, it would take some time. There is nothing from a synthesis capability point of view that NI does that Max can not do. What it really boils down to is making it sound good. Which in the end has more to do with audio engineering, shaping the eq of the sound to maximize spectral content and quality. That's where the real art is. I think NI is notorious for adding their own blend of saturation/limiting on audio before mixing.
