Youtube channel (Your thoughts)

Hi I have a few questions that i hope this forum can and will help me with.

First of all i am a Youtuber and this is what i do atm

I do CS:GO Unboxing with commentary
i do no commentary walkthroughs
I allso upload special videos like all cutsceenes etc etc

My question is it possible to run a channel where i do both commentary and non commentary ?
I do want to expand and make Funny highlights with commentarys from each of the game i complete, is this something that will damage my channel more than it will do good or should i just try it out? or even make a new channel?

i think its worth to mention that i got 900+ subs so it will be kinda hard grinding that up again i guess.

And can non commentary walkthroughs get my account banned? i read about people suddently got banned over night with no chance to appeal or contact Youtube.

Moving to the Youtube/Twitch forum. Please keep all advertisements and questions regarding Youtube channels there.
