I am working on building a new mod for Skyrim with the Creation Kit.The city I'm working on has huge emphasis on verticality and size as well as density-I'm trying to make the most dense and large affluent city mod for Skyrim which has emphasis on using The Gifts of the Outsider mod:There will be assassins using such powers in this city.(My source of inspiration was from the games like Assassins Creed and Dishonored and it's DLC's:A city like Dunwall (not plague ridden) where there are Assassins like Daud's faction.And you'll crosspaths with them.) I'm trying to make the city more accessible through rooftops so that a large portion of combat takes place on roofs in FIRST PERSON VIEW.So my questions are:
1)Is it possible to transfer the powers of The Gifts of the outsider to NPC's (like Assassins) so that they'll effectively use powers like Blink and windblast on combat? More like,when they're fighting you they'll occasionally blink behind you and try to stab you from the back.And,is there any way to script them or mod their AI specifically so that they fight like Dishonored's assassins-extremely fast,brutal and blinks quite often and also use long range attacks with crossbows etc.Any method to tweak their AI making them very complex,so that they'll use a specific power like windblast when they're at a disadvantage with you or blink behind you or try to blink away to escape when they're losing sword fights...etc.
2)Can first person combat and movement animations (like sliding during sprinting,leaping large distances during sprinting or using powers or swinging swords in mid air for making air assassinations,blinking in mid air to survive fall damage etc.) be made on the Creation Kit? Or do I have to use Blender or 3ds Max or Maya for those?
3)Any mod to make a specific map of Skyrim completely seamless with no loading screens during entering or exiting houses,mansions or castles?I know it takes a lot of RAM but won't it be possible with the 4GB RAM mod for Skyrim?
4)I know I sound too ambitious to work on something so big and it seems like it's literally impossible for someone like me who has so little knowledge on the Creation Kit and modding.But I'm going to take as long as it takes and will try to work slowly as I learn more and more things.So I hope you guys don't judge me rightaway and at least help and support me by answering these questions.Thank you...

1) Extremely complex scripting
2) No way without hacking through Havok
3) there is no need for an LAA patch since 1.2(maybe, but could 1.3 too)
So the combat partion so doable but it will eat up all resources the script engine has pretty quickly.
Also it is practically impossible to do 3) with Skyrim.
And of Havok hacking, there no sane person who can handle it besides Fore and Zartar.
Edit: Sorry, I left out TheHologramm from the list.
