Sell it to a 3rd knob.

Brilliant!
In all serious, to OP, 2 knob compressors really aren't that bad. I love my EBS MultiComp and if you have it on its normal mode, it basically is a two knob compressor. Even on Multi Comp mode you can only adjust internally the effect upon Low/High bands in addition to usual Gain adjustment and Compression level. No ability to adjust the threshold, attack, release etc... but it gets the job done and sounds great, YMMV though, might not be controllable enough for you.
