As a prosecuting attorney who selects and works to convince the "average" juror 5+ times a year, this is not a good idea. You are vastly overestimating what the average level of competence is. Most people, when given unfamiliar knowledge work to do, are so hopelessly biased and ignorant that I definitely think the average congressperson is more qualified to do that kind of work. We are spoiled by selection bias when extrapolating what "average" means in the USA.
