I doubt it but you should consult a WA lawyer. It sounds like you missing drinking and driving to me and would probably sound that way to a judge.
The Department of Licensing is notorious in making people use the interlock. They make the determination on how long the requirement is based on the number of DUI incidents you have on your record. The minimum requirement on a new deferred prosecution is 2 years. I doubt that you will be able to get the requirement dropped, and would at least need to complete the deferred prosecution first.
