I found the concept sketches on the left here, which reminded me of EVE ship profiles. The circled chip reminded me a bit of the Megathron profile, which made me think it might make a decent base for a Celestis redesign.
This is an interesting idea. I dislike the specific design presented, it looks too Amarrian.
The Celestis is one of the most hideous ships in the game, but I think it just needs an aft fuselage redesign. The front and asymmetrical nature of it is really nice, but the engine moustache is too much for me.
Luckily the Celestis is not very iconic.
