Not a bad idea, although the king of delay functionality is probably the Intellijel Rainmaker. It's bigger...but you could conceivably fit it if you yanked the Dual VCA and the Dynamix for starters, replacing them with a Codex u4xVCA (8 hp clone of the Mutable Veils) in the Dynamix's spot. This would also open up 2 hp in the top, which could then allow you to put a Xaoc Zadar in for four EGs in the spot now occupied by the one EG in the Contour. More cost, perhaps, but much more functionality!

Another option for the 4XVCA could be the Doepfer A 135-2 which I find super useful and compact. Also, never used the Zadar, but I'd also consider Pamela's new workout.
