If I got you right ... Controling a harmonizer with an Exp pedal would be very hard to achive & non-accurate as well... When using a harmonizer, usualy all you gotta do is setting the right key & the interval, and let the harmonizer do the rest without having to worry about exp pedals ...
Controling the pitch by foot is not anywhere near controling a wah , specialy if there's a big difference in pitch between the highest & the lowest points of the pedal.

Exp pedals with harmonizers are usualy used like a normal Whammy-Pedal ... you only adjust the lowest and the highest pitches that suits your line , and probably you can also mess a little in the middle of both.
