I've been trying to find an E-type front derailleur for my latest build but they're almost impossible to come by. The one I have is for a 26-36-48 and the chain drags on the lowest horizontal part of the cage.

The E-type bracket can detach from the mech, and I've read that any S3/E2-mount mech will work with it. Thing is, I don't know which mechs that are rapidly available are compatible with 22-32 combos.

I'm running a ghetto 2x up front. It's just an SLX Hollowtech 22-32-42 triple with the largest ring removed.

Which part should I get? Doesn't matter if it's SRAM or Shimano or the number of speeds (or even 2x or 3x because I believe they will interchange), I just need a mech that will fit a 22-32 ring config and mount to an E-type bracket.

Quick help is much appreciated!

I don't know what's compatible, but one thing you'll need to consider is that you may not be able to lower the derailleur as much as you think you can. I have a 24-34 double on my cargo bike, and I can't get it lower than 3/8" above the "large" chainring because the derailleur cage hits the chainstay. It still works fine.
