| I'm not sure there are many commercial pedals that do a sequential wah setup. The Line 6 FM4 or M5 (or M9 or M13) have a digital representation of it that works okay though obviously it lacks the control of the ZVex.
Outside of that I think you'd have to DIY what you want.
There are pedals that are in that same realm of sound. The Subdecay Prometheus and Copilot Gyroscope do stepped envelope sounds and there are a few stepped phasers (Boss, Digitech, Subdecay, Prophecy etc). And though much more random and not following a set pattern, a sample & hold filter (Subdecay Proteus, Original Robotalk, a few others) produces a related sound.
Edit: Warwick hit on another option. The MuRF is a great pedal for that sort of effect, though again not exactly the same sound.
I believe the Seek Wah uses a set of bandpass filters which is going to make it difficult to keep the low end. In a blend loop you'd lose the sequenced sound so I'm not sure what the answer there is.
