Well I managed to significantly increase the price, but from what you've said you want I'd start with the below:
Quick notes:
1) I personally wouldn't want a system, small or not, without a Maths or similar function generator. It does too much, mixing, modulation, attenuation, subharmonic generation, etc. There are a lot of days where it's my favorite module.
2) Disting is a great swiss army knife in a small rack and will help you understand what you want in that second rack while adding lots more range to this one.
3) FX Aid is one of the top FX modules with a bit of a community around it, for 1 HP more than the Pico FX which is a lot more limited.
4) Links can work here as your mult (not sure that's needed though?) and also as two different mixers for both audio and CV.
5) I'm not super familiar with Sinc Bucina but NE make good stuff and I think this fits your criteria in less HP than Doepfer.
