Considerably more sense, yes. The choice of the Noise Reap Loafers is especially interesting, since it has all sorts of odd interaction possibilities between its LFOs. Tandemmed with a Maths, that'll be a killer modulation solution.
Not too jazzed on the STO here, though...it strikes me as too spendy, given that you're trying to drop costs. So, let's do several things at once by eliminating both the STO and the Plaits, and adding a Plaits clone by Codex Modulex (saves about $50) and a Braids clone from them as well, which is only $3 more than the STO. This then gives you two VCOs with similar characteristics, which works better for doubling VCOs to fatten up your sound. Then, to hit that Buchla-esque zone, add a Tiptop Fold Processor and use its two inputs as the VCO "mixer", which would put the two Codex clones into a configuration more akin to a complex oscillator. It's a cheap date, too...$135 for a killer wavefolder.
A delay. You absolutely want one now, so that you can properly (ab)use the resonance insert in the A-106-1's resonance path. By doing that, you can create echoes which degrade over time in ways which you control to some extent. A reverb would be really interesting here as well.
The last suggestion here would be to divide paths. Put your audio path in the top row (as best as possible) and the modulation in the lower one, along with the power supply. You want to keep that last thing away from any audio modules to avoid noise leakage. Plus, dividing your functions up like that makes the synth easier to program in the long run, since everything should have a specific place based on function. Going to a 2 x 104 is loads more sensible, too...
