I'm gonna go against the current here and say yes. There are schools out there that seem to interview (I dunno about accept) more nontraditional students, and schools that seem to place more weight on clinical experience. A few of these schools are BU and GW. I am a non traditional student (24 at the time of my interviews) and at least half of my interviewing group at both schools were older than I was, and many of them had full time clinical jobs (as do I - about as many hours as you have). Not all of them, but a significant amount.
My interviewer at GW actually told me explicitly that they care a lot more about clinical experience than research experience and that based on my application alone he thought I was a good fit for the school (this was at the very beginning of the interview). I did get waitlisted so keep that in mind, but I did not send in any supplemental letters of interest or anything, and I hear GW likes to see applicants show interest.
