I know this is an older thread, and I've posted this suggestion elsewhere, but I think this is the right place for me to make such a suggestion.
I think it would be very cool and very doable to add sequenced modulation (Like the ZVex Seek Wah, Seek Trem, Ringtone, etc. Or the Roger Linn AdrenaLinn.)
Probably some of the more famous examples of sequenced modulation would be the intros for "Bigger Than My Body" by John Mayer or "Boulevard of Broken Dreams" by Green Day, both of which used an AdrenaLinn to get that sound.
Couldn't the Modfactor just borrow the sequencing algorithm from the HarPeggiator effect in the PitchFactor to achieve this?
