i'll have to go back over both the manga and anime to comfirm this when i have the chance.. but im pretty sure Kakashi said that the sharingan couldn't copy ANY jutsu where a KG was involved in its creation (like haku's ice mirrors)..
but lets play along with your theory shall we and use Naruto.. only your chakra mix proportion is totally off for Mr. Uzumaki..
thanks to the kyuubi's ever present mixing of its chakra into naruto's chakra pool (eventually becoming part of naruto's base chakra reserve), naruto has quite possibly an order of magnitude greater chakra than just about everyone in the manga (outside of the other bijuu hosts, Nagato, Kisame and perhaps Madara). AND that's before even adding the fox and sage mode into the mix.
so for this example, where you say haku has 47 parts wind, 52 parts water and 1 other.. we'll assume naruto has (just for the sake of argument here) 5 times each what you pose for him (and again, we're assuming water is going to be naruto's second affinity).. again, contributing to his incredibly larger chakra pool. Assuming he knows the seals required and has the proper chakra control (and for this example, we'll use non sage mode naruto as of the last few chapters of the manga.. the fact that he has mastered sage mode in my eyes tells me he would have the required control), by your theory he 'should' be able to perform Haku's KG jutsus.
and also, dont forget that the only element we've seen Kakashi NOT use is wind (to my knowledge at least).. so with that in mind and given his chakra pool and control, only the dojutsu specific KG jutsu would be out of his capabilities assuming he knew the proper seals
agree, with this guy ^_^
