Saints making a push to sign Cooper Kupp [Cooper Kupp signs with Seahawks to a 3-year, $45 million deal]

I agree with this. Moore schemed Smith wide open in Philly. I think he can do the same here.

This is where Jeanty at 9 makes sense. Add Jeanty to the backfield to assume RB1 carries allows AK to evolve to more of a weapon who is also a RB. That's 2 players for a defense to account for. A Big X WR (Savion Williams/Jayden Higgins/Tre Harris) would be 3. Shaheed could be the 4th, but I like a Big Z, maybe Dont'e Thornton out of Tennessee. Some think Tre Harris could be a Big Z since his route tree is limited right now, but he doesn't have the top end speed. A receiving threat at TE would also be an option and CKM has shown to use them, JJ or Moreau could fill the roll if we don't add someone in the draft.

I think there are options to do exactly as you are saying. The goal would be to keep Olave clean. The good thing is his speed and route running would help keep him clean as well depending on the play design.
Based on what you pointed out, the Saints are close to having the players that would allow Moore to move all 5 eligible receivers on play all over the offense alignment.
