It's not that simple, nor is it a "5 minute fix"
The first person camera uses the same exact skeleton for all the races. So you modify it, it modifies every race.
In other words, it requires a complete re-programming of the entire system.
Did you actually read those mods? You have to choose a height. Because it cannot adjust for any race. Because they all use a universal first-person skeleton. I agree, it is unforgivable. But to say that it is an easy fix is false. Did you notice the Skyrim Script Extender REQUIRED?
That is not a 5 minute fix. And for consoles, that's like, complete re-coding.
