You think its possible for Mitsuki to clear the mist with his Wind great breakthrough technique?Without zabuzas hidden mist jutsu yea possibly, even more so with konohamaru(assuming he's earned his jonin status) with it they could possibly beat them with konohamaru, but def not without. Hakus mirrors are an issue, but there's 3 of them(4 with konohamaru) and they're all smarter than naruto was at the time, so they've got a better chance(sans plot kyuubi of course)

OFCOURSE!
Boruto>>>>>>>>>Naruto
Mitsuki>>>>>>>>>Sasuke
Sarada>>>>>>>>>Sakura
why wouldn't they beat Haku and Zabuza?

hell naw!..
Haku was handling Naruto & Sasuke who has bijuu power unchecked & 2tomoe sharingan.. If you think Mitsuki is superior to Naruto & Sasuke then it's on you..
Zabuza would wipe the floor with Konohamaru.. He hasn't shown anything to think he could keep up with a Zabuza..
Zabuza could take Mitsuki & Konohamaru on his own & Haku would/could handle Boruto & Sarada..
Team Kakashi is superior to team Konohamaru in those states..
Team Kakashi would've wreck that shoji or whatever his name is real quick.. The Sauc alone could've handle him..
