The value of multiengine time is two fold. First, if you don't meet the hiring minimums, you'll never get to explain why it shouldn't count so highly. Second is that you'll have to overcome any bias that the interviewer has toward the question. Interviewers tend to hire those pilots who look like themselves. If the guy who interviews you has alot of multi time, good luck trying to explain it to him. You may find this will be the biggest hurdle to overcome.
