Need help to make a challenge mod

[DiscoDragonFTW]

I have an idea for a challenge mod for a YouTube video series I want to make "Can You Beat Skyrim As a kid?" the only problem is As I want to do things with this mod that I don't know how to do like modeling the armor to fit on kids and then creating special vendors that sell them and making non-shrunken armor unwearable I also want to make all hair available to all the Kid races in the race menu as well as set all skills to 0 (except for the ones you usually get as a race being brought down to 15) I wouldn't want this to have to depend on anything like the unofficial Skyrim patch as I would want this to be as vanilla as possible. I would also need help making first person models for those armors and child's clothes. please hit me up on Nexus If you think you can help me
