I'd suggest CEM3372 (or similar) as VCF/VCA.

As Samppa mentioned: the highpass CV is one source to get additional CV 
control. The other is the DCO-balance. You might modify also the 
waveform setting of the DCOs in a way, that the setting for the 10/90 
pulse works as "DCO-off". Now you have freed the DCO balance CV. If you 
get down to saw only DCOs, you would have another prgrammable switched 
control.

I think, soundwise the most interesting modding for an analog 
subtractive synth is to modulate the VCFs cutoff-frequency (in the case 
of JX3P/MKS30 with DCO-2). I tried it already with one voice. It 
requires to amplify the signal level of the DCO, but it sounds nice.
