FMQ with a treadle could be a challenge, but, if you can darn with it, then FMQ is an option.
However, I have tried covering feed dogs one time with a hint I had read somewhere -- tape a recipe card over the feed dogs, remove the foot ...
well, the card and tape interferes with the movement and dodging the needle without some sort of foot is a bit more dicey than my little heart cares to handle! <g>
