Beautiful sprites !
Do you mean chassis options? Or new ideas for their gods?
Regarding the first, and strictly thematically speaking (can't give you advice gameplay wise), I would say:
A sacred statue, as for the holy mother
Divine Glyph, representing Logos
Forge Lord, for the crafting theme
A Virtue, an Arch Seraph maybe
A Titan, he looks like in the Michelangelo's picture
