Do it! I'm a former border turned skier.
I'd say I was probably an advanced beginner border before I stopped; and never got comfortable with speed. Could get down on double blues at Jackson Hole, but it wasn't pretty, haha.
Currently early 40s, and switched to skiing in my mid 30s. About...two seasons after I switched, I blew my ACL/MCL skiing and had to take a break; which was prolonged due to pandemic. Last season was my first full season back after ACL reconstruction/rehab.
When I picked up skiing for real, it was much easier than learning to SB or the first time I tried skiing—prior to my SB years; was two terrible lessons... I already knew how to edge control; knew the basic rules of downhill/snow sports was not as afraid of speed or having to weave around people.
I did, however, have difficulty with remembering there were now double the edges PLUS poles... not just two edges of SB. During initial switch from SB boots to ski boots, plus having to carry 4 items vs 1, I'll say is very annoying. But you quickly get used to it. Keeping poles in correct places was a bit challenging but I've noticed once you start getting your edges engaged and controlled my arms naturally did correct movements with poles.
Absolutely hated rental boots. I prefer stiffer boots with traditional liner over intuition/heat-mold because they are more responsive to my hyper-mobile feet and have less pain with proper insoles and fitting than what I experience with a heat-molded intuition liner.
If you do buy a boot, consider ones with walk mode, they help a lot when you first have to switch from SB boots. Now I don't even bother engaging the walk mode, but during the initial transition period, I really liked using the walk mode.
So... 2nd full season in, probably 4th ski seasons total, I can link multiple parallel turns sometimes, but often have to cheat and pick up my uphill ski or will start off in wedge turn on the uphill ski and parallel on the straight portions. Can do greens and easy (mid-atlantic)blues...
