I actually think the use of the Little Nerd in v.2 of the rack makes more sense. It has a lot of the Pamelas' capabilities, plus a few extra tricks, but occupies less space and it's more cost-effective. If this version of the rack is the direction to go in, the only change I'd think might be in order is to remove the Moddemix (the Wogglebug has a ring-mod mode, and the Erica mixer takes care of summing), then drop in a 4 hp multi-drum module that does more conventional rhythmic station-keeping while using the NE Pilobolus Vomitorium Excelsior as the source for screwy percussives to contrast with the more normal ones. In that 4 hp range, janost has a number of short-run clones of 4-8 voices of classic stuff, like 606 and 808 modules, an Oberheim DMX-based module, and a few other bits of trickery. Plus, by going with a 4 hp drum module of that type, you have 2 hp left...which is perfect for dropping in a 2hp dual VCA module, which you really need. VCAs are sorely lacking in this build, but that may well solve the issue and give you a final version of the skiff.
