I am thinking of building a modular row with 114 HP around the mother 32.
I think it needs:
1. Maths (alternative: one or more functions or 171-2),
2. another oszillator (E330),
3. one LFO (E355, A-147-2),
4. Power solution (uZeus?)

Do you know any modules that I am missing, or can do better?
If I would go for maximum module count the erica synths pico series would be an option:

PS: the uZeus only uses half of its mA with this row. Is there a way to power the whole row with the Mothers PSU?

Looks like this at the moment:
