Any mod that changes and improves the appearances of Solars and Deva?

[Morgoth]

Kinda odd to have them be the same.

I didn't tried it yet but this component of Random Graion Tweaks:

Component 1001 Change Planetars to use their SoD solar-based artwork

SoD included Planetar animations derived from the Solar animations, but these animations ended up unused. This component assggns them to the actual planetars.

COMPATIBILITY: This component uses static monster lists, so please report if a planetar was missed. This component can be combined with the animation components of P&P Celestials and Spell Revisions, if you install those first (it will not touch the devas).

sounds rather good.

Spell Revisions has a component to change the appearance of devas. PnP Celestials changes them as well. 

Be aware, for some reason the celestial summoning limit is tied to their particular animation. Changing their appearance removes the limit.
