I think you're still capable, just with that interval between use, you're perma-rusty at handwriting. My own experience is that I have retained the ability to learn scripts well into adulthood.
Within the last few years I've done what I call "installing a font." I was unhappy with my printed letter forms, so I looked up architectural lettering guides and modeled my new printing based on that. I also re-learned how to write cursive, which is always a struggle any time I re-start using it after months of having not.
Yeah, my father had lovely printed penmanship. I've planned on practicing to develop that as I return to reading more (in retirement), both to take notes as I read and learn, and because otherwise my notes will be illegible. My current hand printing or writing is atrocious.
