Firstly - Mavs work with Dwight on a new contract. Decline PO and come back for a 2-year vet minimum AT TRAINING CAMP. DP would lose $400,000 in 25/26 but would add an extra year at $3,600,000 in 26/27. He also get the chance to see if there's a better deal on the market.
If DP agrees to that, Mavs get under the 2nd apron, and can now aggregate trades.
From there
Nets get Gaff into their trade exception for #19 & #27. (Allowing them to shop Claxton)
Bulls get 2 of Caleb/OMax/Hardy + #27 for Lonzo
Mavs get Lonzo + room under the apron to offer CP the TMLE and #19.
