Nice!! Why not try recording a band with all 400 mics. Throw the first 100 on the drums just in case. You can never have too many mics on a drumset.
Actually one of the nicest drumset sounds I heard was made with a single mic. - a Soundfield.
Though it did lack the kick drum a bit - so I would say two mics: a Soundfield plus one for the kick.
