1. Not crazy at all. Great idea; it has come up a number of times. Here’s just one:

More & more manufacturers must think so, too. There are some straightforward methods available now that provide this externally, via MIDI or expression input.
2. There are a few options that’ll get you a little closer, depending on exactly what you’re after. Reverse (delay) before Q-Wah, TremoloPan into any dual effect, HarmaDillo into Q-Wah Envelope… stuff like that.
As for the dry mix, have you considered using the Program level Mix with Q-Wah? Again, that’s going to depend on what else you may be using in the other Preset, Series / Parallel routing, etc. But it’s something I use all the time for blending, along with algorithm Mix parameters.
