My first question is what your current research experience looks like. Have you spent much time in a lab or have you done much bench work? I think it's one thing to read papers and be interested in research, and another thing to be the one at the bench actually getting your hands dirty. I had a lot of TA lab experience but pretty minimal research experience before starting - I'd done a summer internship with a forestry lab and shadowed/volunteered in a virology lab. I thought I loved bench work. I've been in my program for 9 months now and I'm way more interested in the bioinformatics we do than anything else. Point being, you might surprise yourself by what you like/dislike about research, and that might change your career goals.
As far as being a PhD without being a PI - it sounds like maybe the job you're envisioning is a dual research/diagnostic appointment? Although the anatomic pathologists I know who do research and teaching/diagnostics are either the PI of their lab or joint collaborators with other researchers and share grant writing/etc responsibilities. I definitely don't know much about that world. Paging
