Liking how you think, sir.
It's not exactly a popular opinion but... I really don't have much interest in signing Clowe or Clarkson. They're glorified 3rd liners who are going to be paid like 1st/2nd liners. Considering we have Bourque at 3.3mil, Pacioretty at 4.5mil and Plekanec at 5mil, what sense does it make to give one of these guys 4.5mil over 6 years (seems to be the asking price)? They are both very streaky, physically and production-wise. They aren't fast, they aren't heavyweights, they don't bring offence - they are offensive because of the players on their lines. They open up space but honestly, we've got speed to do that. Horton is probably the best option for the 2nd line, similar to Bourque. Too much of a caveman for my taste.
It is a common misconception that Clarkson is a scorer. Look at his stats. He has scored more than 30pts twice, he's scored over 17 goals once. Don't think anything has to be said about Clowe and his offensive contribution.
If we are going to sign 3rd liners, let's sign 3rd liners and pay them accordingly. Bickell and Stalberg are great options, 27yrs old, similar production, could both be signed for 5/6 years 2.5 for Bickell, 3.5 for Stalberg and I wouldn't feel unhappy about it.
Another potentially unpopular opinion - Bring back Lapierre. He's actually turned into a pretty good player in Vancouver. Let him run his mouth and get knocked around so Gallagher doesn't have to. Hits, good defensively, decent size.
Loving the inclusion of Cody Franson. He can run over guys pretty good, this is true. May not bring spectacular defence but he does bring physicality, something we lack. With Subban, Franson and Emelin able to lay out huge hits, makes opposing forwards a little more tentative. As you said, also brings offence, no more Bou-Bou on the PP.
