Is it possible to have too much ripple capacitance? Has anyone played with using a large IGBT instead of a bunch of MOSFETs? Thanks in advance!

I can understand why you haven't read all the pages, its a bit of a marathon.
But the point of the caps is to achieve sufficient "surge" capability with the lowest ESR possible and the values chosen do that. Also at an affordable price.
The files are here:
Open ReVolt/PCB Schematics - EcoModder
And yes, people have played with IGBT versions.
