HFS+ in Windows for Multi-System NAS?

I have a desktop PC set up in my living area that I have on 24/7, and I have two Mac laptops that my wife and I use for most everything (the desktop is primarily for gaming). Since our music and photo libraries are sizable enough to necessitate offloading to an external drive, do you think that it is reasonable to internally mount an HFS+ drive in my desktop Windows computer and share it on the network for my Mac computers to use? This is of course using Paragon's HFS for Windows program which I already own alongside NTFS for Mac.

This would be especially ideal because, I could then have iTunes running on the desktop PC and available as a shared server - and potentially do the same with photos someday, if I ever switch to a multi-OS program light LightRoom.
