Texture Pack Mod Support Ideas

I'm going to be adding Mod support to my Texture Pack: 21st Century-Craft, which you can see here: http://www.planetminecraft.com/texture_ ... ury-craft/

I have been thinking about the Aether Mod, but considering its in heaven, there's not really much i can do to adapt it to my Texture Pack.

So if anyone has any ideas for mods I can add support for, let me know
