That's fine,
Did you buy this account it sounds like it:
You can download piracy videos, or anything don't overthink it, I think you're over thinking it.
If you're at 0 subs you need to overthink it, if 1000 you need to make sure monitation is enabled but be warned don't upload Disney only movies that are b grade:
Example Jason Staphm, or random ass movies, just upload them on your phone and that's it.
Do some marketing at the library make it a fun day. Do some editing here or there.
Your in a good situation you just need alot of ideas.
Just as I said only upload piracy crap on the old channel, the new channel can be you uploading a image of rain videos nothing to complicated even a still image.
You can even do shoutouts here, sell one of your old channels and get a jr junior badge, and help boost those wanting to get viewers here and pay like $5 per a boost.
You have tremendous opportunities.
