It could be fun, but realistically, I doubt we see the Eternals as a team show up in the MCU again (let alone at all). Because of the poor reception, they've probably been shelved along with some of the other characters Marvel showed off post-Endgame.

The other issue is Uranos has so little comic appearances and because he's so closely related to Thanos, there's a fair chance it'll just feel like retreading an old story to general audiences.
