Dude...

- There is no amount of training that can make up for the loss of the sharingan

- He uses it in every single important fight he has

- ... no he couldn't, the raikiri would be countered just as easily as naruto's rasengan if kakashi didn't have the sharingan ( go read the gaiden )

If he does lose the sharingan at any point it will be in the end, when he doesn't have to fight anymore ( either a happy ending or him dying )
