With your budget and needs I would only suggest a few adjustments...If I may-
RYTM (perfect for you and your tunes IMO)
Twisted Electrons Acid 8 or MAM MB 33 Retro (instead of Avalon)
Virus Snow instead of JU-06 and Volca FM
Eventide H9 (core is enough, max is awesome)
Strymon El Cap (GAS)
Octatrack instead of Electribe (also replaces Avalon sequencing)
MF 101 x1 and
Moog Slim Phatty (synth that can filter external signal and be heavily controlled/manipulated by Octatrack)
MacMillen QuNexus/Keyboard and Kenton USB Midi host
Midi Solutions Quadra-thru (powered by Octatrack, better than going midi thru)
Behringer mixer (model that fits your needs)
Pedaltrain Terra 42 to carry it all around.
RYTM and Octatrack seem like a match made in heaven for you. I know you already owned one, so you know what you are getting. Virus, while not analog does the sounds you are after with the Juno quite well, in addition to being a great FX processor and all the other forms of synthesis you can do on it- it is a very powerful module and has an equally small footprint. And it will run circles around the Volca FM no doubt. I suggested the cheaper acid boxes well...because it's acid, not rocket science, and I think they sound pretty good. Can sequence either from Octatrack. Eventide H9 for reverbs...just sublime really, it is always on. Slim Phatty instead of an additional Fooger because it's a synth and a filter that the Octatrack can surgically control. Run your acid machine through it and P-lock or LFO the cutoff, res, env, etc...QuNexus because you need at least something to play on every once in a while and its form factor fits Elektron's perfectly (almost exactly the same width) so it fits in a compact rig well. Kenton converter over MacMillen because it works with everything instead of just MacMillen units.
For a live setup, there is nothing in the world wrong with buying a Behringer mixer IMO. I own 2 that I have owned for over 10 years and used extensively over that time. They are built like tanks and have the most ins and outs and sends per channel per dollar. The pre's are sterile which for live I view as a good thing personally, although the eq's are also sterile, which I do not like as much. My Soundcraft EPM 8 has lovely pres and EQ's but it is larger than I like to use in a "leave the house" rig. There is a 6 channel model I may end up getting.
Anyway, that would be my take on your idea. Pretty sure it's still in budget and depending on the mixer you choose it would all fit in the case hooked up and ready to play. Good luck building your live setup.
