[Naruto] Why doesn't Might Guy amputate his leg and get a fake one like naruto's arm?

I get the whole DR. House angle where you don't want to lose a limb, but if you have a replacement that works just as well as the original like Naruto's arm, why doesn't he get one as well?

Naruto's arm is made from Hashiramas Cells, the experiment Yamato is from shows that most people die instead of integrating his cells into their body, so it would be really risky to use it on people without special chakra.
