Here's how I see it:
Example #1: Beyond Skyrim: recreating all of Tamriel in Skyrim's engine. I would donate massively to this.
Example #2: Fishing mini game which was listed at $2 on the mod workshop when it existed: No donation.
Example #3: Everything in between, such as new quests, armor, graphical improvements etc. My donation method would be dynamic depending upon what kind of effort I thought they had put in. I would reward effort and talent.
I guess I didn't exactly answer the OP but if you extrapolate this answer you see how I would see it.
