Share Private Posts to Public Channel, Community Activity Stream

I am trying to build my education community, I will use Channel Public as Activity stream for community members, then a Private Channel for each member and their related teacher or staff moderator.

Is possible request a Share To Public Channel feature, that let Private Channel member share posts from Private Channel to a Public Channel?

That posts shared to Public Channel will convert in a public privacy item that let Public Channel members comment and react on it.

Then from Private Channel, that item shared will labeled with a icon “Public Privacy”, that will alert members about that item can be see by Public Channel members.

That workflow let us create private conversations for community and a public Activity Stream to have all engadget.

Another feature is, from Direct Message members can share posts to a Public Channel.
