The only PharmD/PA I've ever heard of was a pharmacist who worked in a rural location and did PA work on the side. I don't really know how being a PharmD/PA would be practical aside from being a super mid-level practitioner, but that likely won't result in a pay increase and you've done more schooling than an MD/DO to work as a mid-level.
Who knows, it may help you find employment though and set you apart from other applicants.
