I think I would second your reduction of the Rainmaker to the DLD; especially as you have iOS integration and can get some really, really nuts stuff out of whatās available in that direction. That would let you keep Braids, or go with Batumi an some of your attenuation/mixing thatās unavailable in the 6U rack you showed.
As for me, I recently downsized as well (though not in and much of a significant manner!) from 180hp to 120hp (6U to 3U). My former rack:
and my current:
(with some passive modules sitting around in little boxes)
Going with the momome stuff outside the rack is what spurred most of that, so that significantly frees up the ability to go small. Plus, I had a gig two weeks ago where I just showed up, pulled my case out, plugged in my mixer and was ready to go. That, for me, was the main reason of going smaller.
