I wonder if there isn’t some POG 2 in there as well. You could probably cover all of the above in Polyphony & Auto EQ. Or VocalShift, if you’re feeling adventurous, and want something to build those chords out of single note lines.
Worst case, use both H90 slots to break up the filtering & slapbacks into two components. The delay portion sounds somewhat like a brighter multi-tap to me, as opposed to a short delay with rapidly decaying feedback. Again, you could probably simulate that with dual delays offset in time from each other. Or substitute MultiTap UltraTap with a few Taps.
