The above build with all of the Renes doesn't strike me as a very well-considered idea. I see no VCAs, for starters, and a lot of the other necessary items are totally missing.
If you want this many sequencers, you either need a MUCH bigger cab, or you should just chuck the idea of using sequencers in the synth altogether and get something that's a dedicated sequencer device, such as a KOMA Komplex. Occupying this much room with Renes...especially with what's NOT here...seems like a recipe for an expensive and unusable disaster.
