Going to make an Alduin mod

[Gundalypse]

I just finished the main quest again and.. wow, I don't know why I think it would be different this time unless I do something about it. So I am going to build a mod to beef up Alduin. I know World Beater Eater is out there but I don't particularly like that mod. I want to build Alduin to be more like a boss from one of Vicn's mods or like what Kittytail has done. I am looking for some good ideas. Nothing to the extent of WBE, just some scripted attack ideas. Phases at health percentages possibly. Maybe an add phase of skeletons or something. I dunno! Ideas would help.

Thank you!
