My bet is that an "investigation" would show zero of interest. I think all they edited out was probably the legalese explanations of how to do what they are proposing doing and stay within the very forgiving and very flexible laws on the topic.
It's a Twitter Twit Talking Point that Super PACs aren't allowed direct dealings with campaigns. This has been discussed ad infinitum and there are limitations but it is all in the area of "it depends on what the meaning of is is" territory.
There is no way they sit around talking about colluding in an illegal manner. That conversation would get shut down by one or more of the conspiracists. They're sitting around a meeting room table openly discussing the candidate's approval/involvement. I doubt it's illegal.
There is nothing to prevent the Hillary Campaign from launching a Donald Ducks campaign. They wanted to do it at arm's length. Just where that line is drawn, legally, I'm not sure. I doubt anyone raising a stink about it is really sure, either.
Damage, on a scale of 0-10, with 10 being "Grab 'em by the pussy!": 0
O'Keefe's on the edge of a career milestone. He's delivering on the money invested in him (Donnie the T being one of those contributors) but his product is shoddy and dysfunctional. He's lucky he got donations/contributions from the black money pool. Otherwise Donald would stiff him.

He's now barely a distraction and better find himself a Stoessel-type career at the TrumpBart Network, because as a political operative he's a waste of money.
