Gotta agree here - an envelope filter relies on dynamics to drive it, and these will (at the very least) take it down. If you really have to place it close to the end of your chain, I would go with one that is easily triggered - the Mr. Black Fwonkbeta, the EMMA DiscumBOBulator, and the various 3 Leafs come to mind. You may also want to experiment with the effects loop .You really should consider experimenting with different placement of the filter. compressor before an envelope filter will limit the response and range since dynamics is a way to play the filter. A limiter or comp after the filter is a way to even out the peaks that can happen with said dynamic playing. Same can be said for the distortion/drive as each will have a different character.
Good luck!
