Either way, welcome to the forum/conversation. I think we're all so used to people sharing their racks here for the sole purpose of starting a conversation and getting guidance.
Branches might be neat for adding some random variation to your triggers, and something like the Klavis Mixwitch might be worth a look if you do decide to invest in a switch. The Mixwitch does a few different things in a small footprint. I've been amazed with the sounds I get out of QPAS if you decide to add another filter. I may have overlooked it, but something like a Doepfer A119 envelope follower might be useful if you are incorporating external drum machines... Just one of those utilities I didn't think I would use as much as I do.
Have fun and good luck.
