too many tracks

Remember that British March I needed to produce? Well, I finished tracking it yesterday with all the guys in my department. Now bear in mind -- these guys are VERY accomplished musicians, but for this tune, I was asking them to play instruments that many of them haven't played since high school! To add to the confusion, instead of tracking them altogether like an ensemble, I tracked them each one at a time, overdubbing and multing all their parts! I now have 31 tracks of wind, brass, and percussion instruments, that have to be combined with the sampled tracks of winds, brass, and percussion instruments, and need to end up sounding like a real live ensemble?!? Wish me luck!
