Again, very few undergrads will have true clinical experience. Especially if you are applying to research-heavy programs it is unlikely professors will place much emphasis on it...even equal emphasis programs traditionally give far more weight to research experience because as I said, you can't get much in the way of "real" clinical experience as an undergrad because the only things you are adequately trained to do are very qualitatively different from the role you would take at the doctoral level. I'm in a PCSAS-accredited program right now and had zero clinical experience when applying, but worked in 5 different substance use/addiction labs, all with federally (R01) funded investigators, was on a first-name basis with all of them, got strong letters, and played a significant (and unique) role in each of their labs. Our faculty here have openly stated that clinical experience is certainly nice to have, but its not by any stretch of the imagination a deciding factor in applications, and too much will actually hurt you (especially if it looks like it supplanted research experience). If these are the schools you are looking at there is no need to try and twist something into clinical experience if it doesn't fit. If clinical opportunities are there, by all means getting SOME experience would certainly help, but there is no need to force it.
