Just throwing some shit at the wall:
-Jarry to San Jose for Blackwood and Tampa's 2024 3rd
-Smith at $3 million to Vegas for McNabb
-Tampa's 2024 3rd and Nieto to Ottawa for Joseph
-Sign Lafferty (2 years at $2 million) and Lindholm (2 years at $5 million) in UFA
-Re-sign Puustinen (2 years at $1.5 million), Poulin (1 year at $800k), St. Ivany (1 year at $800k), and Nedjelkovic (2 years at $3 million)
O'Connor-Crosby-Rust
Bunting-Malkin-Rakell
Joseph-Lindholm-Puustinen
Lafferty-Eller-Acciari
Poulin-Puljujarvi
Pettersson-Karlsson
McNabb-Letang
Graves-St. Ivany
Ludvig
Nedjelkovic-Blackwood
This has them at $770k in cap space for next year with a cap of $87.5 million. I think Lindholm for 3C may be a bit unrealistic, but at the same time, he didn't have a particularly good year this year so maybe a short term, higher AAV deal is something that could work.
If O'Connor falters on L1, you can bump Lindholm into the top-6 and O'Connor down to 3C, or you can bump Eller up to 3C and move Poulin or Acciari to 4C.
