Kakashi didn't really hit Kage level until Part 2 tbh.

Only enough reserves for 4 Lightning Cutters vs well over 6?

Only enough reserves to use the Sharingan for one battle before being bedridden for a week vs being able to fight with the Sharingan for hours to days without stopping?

Etc.

Although I don't agree with @Rachin in that it'd be low difficulty, Naruto and Sasuke would most likely win. Their amps put them at around Jonin level, and even if Kakashi was a high level Jonin at the time, he's only one Jonin. With smaller reserves than Naruto and arguably Sasuke.
