I think it would be fun to do. ∑d(°∀°d)

Plus it helps spread the word about said artists throughout the fediverse. (⌒ω⌒)

Though as part of the addendum, maybe also add [FediFriArt] or [FFA] in the title? (•ิ_•ิ)?

Could look like this:

[FediFriArt] Kitsune is long-winded! [M] [Annoyed Artist]

Or

[FFA] the fox wouldn’t shut up! [AintIaStinker] [M/M/G/A/F]

This way it shows it is a promotion of art from artists from across the Fediverse on Fridays here on Yiffit. Though like you said, this should be optional and people should be able to choose if they want to participate. (⌒‿⌒)

That sounds like a good time, actually. Really like the idea.
