I'm also of many mixed feelings on this.

I don't really want to see somebody else tackle the role, and agree that many of the scruffy elements of Han's world that we know of i.e. smuggling, slavers, crooked dealers, the Hutts, running on the edge of the law, completely interfering in governments and murders would all be chucked out.

So I'm thinking we're really not going to see much Corporate Sector Authority action. Perhaps some bits of stuff like came out in the Bantam HS trilogy that directly reference the OT and blatant "how a young character gets to be his famous older counterpart" schtick.

...

But as long as they have Han say things like "Stang!" we're headed in the right direction. ;)
