You would need two EGs that trigger on end of envelope, and your A-141-2 VCADSR / VCLFO does that, but only does one. You would need a quad polarizing mixer like the A-138J to blend the functions, but I didn't spot that here. And then I guess something else to mix and invert the outputs.
But it's good because if you drop the A-141-2, you only have find 6hp more to sacrifice to fit a 20hp Maths.
Oh, you wanted to get rid of some modules? We don't do that here. We only get more modules and larger cases.
