Distributing Editor Tools for User Generated Content (for Steam Workshop)

This one's a bit of a license question, please redirect if there's a better place to ask this!

I have a level-based game, and we've written a custom level editor within Unity to easily build levels for our game (tile map editor, enemy waypoints, etc). I'd love for the community to be able to use these tools. Can I make a Unity package with these tools, and then folks can create and export levels from that? From a technical standpoint, I know I can, but I'm wondering more legally, since I imagine most of the UGC would come from people with the personal edition of Unity. Anyone have any insight?

Thanks,
-Mark

Footnote:
"Why don't you distribute your level editor tools inside your game, or as a separate executable?"
I'd love to, but certain features critical to our game's function and performance (NavMesh generation and Occlusion Culling generation) are available only in the Editor, so without ripping out Unity's native features there and replacing them with an asset store or home-grown version, I'm out of luck. Having tools in the Unity editor that run these steps on export is my only feasible path forward at the moment.

 

Hmm, anyone know? If not, does anyone know a better way to find out the answer, a legal email contact or something? I'm eager to start working on this feature, but I'd be pretty bummed out if I built it and then found out I was in breach of the license agreement.
