I don't think Moog Modular have something like this

(I think Moog have some trigger modules of some kind, but i don't know if a Moog Modular can do all this in some way. I would like it.)But two ways (positive and negative) modulation inputs for all the individual ADRS parameters in all envelopes including the VCA envelopes should do the trick and more - or am i missing something?
In other Arturia applications the Modulation Matrix can be used, but in modular i think it's better if each parameter could have a modulation input. However a mod input needs GUI space, so perhaps a Matrix to modulate the envelopes is needed.
Some new xtra and bigger envelopes that can be modulated can do some, but i would like the mod possibilties for the VCA envelopes as well.
No doubt the possibilities would be useful to have in Modular V.
Also in ARP 2600 V for that matter.
