You can charge whatever you like, of course. Most artists undervalue their work. If you put in the time and effort to produce a product, you deserve to be compensated.
But ...a lot of people in this hobby will balk over $5 and will just walk away. I have a vague memory of someone (possibly more than one person?) doing this at another store years ago, but they were charging more for the Poser versions of items. People were really angry about it. No one likes to feel they’re being punished with a financial penalty for using their chosen software.
I see there have been a few posts since I started replying...
Having said this though, being 99% a Poser user, if I see a product I really need that is Studio-only, I might buy it anyway and just do my best to convert it for Poser.
