Filters aren't the only way to affect timbre, and you could probably get more mileage with just that JP-6 filter (having an actual Jupiter-6 for the past 30 years lets me be pretty confident with that statement) and some type of CVable waveshaper, such as Tiptop's Fold Processor. That would give you the same timbral flexibility as the distorter in the Dystopia...and then some! But as for having three VCFs in that small a build...well, that just makes no sense. You don't have the luxury of massive panel space. The ideas here are on the right track, but you need to keep your space constraints in mind in this small a cab.
