Hi Sajmund,
Well you know what's the saying that goes around here, right?
You never can have enough VCAs
Though your approach... yeah, that might be just about enough ;-)
So what you could do is, you completely clear out your living room and then for each function you fill up one rack like the above with all VCOs, then another rack for filters only, then another one with LFOs (you might want to combine them with EGs) and a rack full with mixer might be helpful too. The one full with VCAs, you got already.
If your living room has more space, also get one rack full with sequencers only, one with logic modules only, one with effects modules only, one with percussion modules only, etcetera... It is actually a nice idea :-)
Unless you just won the lottery or you are otherwise a wealthy person, it might have here and there a few financial issues your plan but other than that, yeah, go for it :-D
Kind regards, Garfield Modular.
