Sorry for the late reply, but you should be able to...but Studio One will not find the normal .dll in your VST folder, you will have to move the full version of EZ drummer to the VST folder within the Studio One folder (in windows, not sure about mac).
Easiest way would be to test it with a free VI to see if it does work. I have had success with this in the past, though cannot garentee anything, YMMV.
I know this is late but I have studio one artist and I upgraded to full ezdrummer + dfh without a problem. I to could not find someone that had actually done this. So I took the chance and it was successful for me.
