i think yes
kakashi will get power up surly and this eye is the only choice
if you can notice,kakashi is the only character who got power down to his form in the start of the series
also if not,how will they get out from this dimensions without kamui?
i dont think he will get both eyes ,it isnt kakashi style ,i think he will restore his past eye then fuse it with his normal eye which naruto made,then he will have ems or rinningan ,may he’ll fuse both eyes first
