I'm not sure you need the DCA half-veils in there, especially with two FULL veils! That would save another 4HP, leaving 10 total free for something else.

It fits, though. Given that the topology of those VCAs has that variable curve, it's best to have dedicated VCAs for the modulation as those will need to be used in linear mode (or something weird), while audio requires an exponential VCA so that the level changes conform with the psychoacoustics of how we perceive loudness.
