Hmm … swept combs. That might be what you’re missing. I *believe* you’re only going to find that as such in ModEchoVerb’s modulation choices, and even that wouldn’t have the same depth of detail. It’s pretty much locked in after the reverb.
That said, there are a bunch of multi-multi-chorus modulation Programs over at PatchStorage. Maybe one of those will get you closer. TriceraChorus is a popular programming target there, but I’ve seen builds using all kinds of chorus effects (many taking up both Preset slots).
