Yes I would take both players, but I'm not giving up much for Rudy Gay. I'm hesitant to give up our 2016 Brooklyn 1st. I'd rather offer SAC the better pick of the 2017 swap between us and Brooklyn; as well as the 2018 Brooklyn 1st.
Due to previous trades (picks owed to CHI & PHILLY), I think Sacramento has incentive to complete a trade for Cousins now:
1) Sacramento owes it's 2016 1st round pick to the Bulls if the pick is between selections 11-30. The Sixers have the right to swap 2016 1st round picks with the Kings (if the pick is between selections 1-10). Philly could swap if Sac ends up with a better lottery pick.
2) If Sac doesn't convey a pick to the Bulls this year, they will be obligated to in 2017 (if the pick fall between selections 11-30). Once again, Philly would have the right to swap picks with Sacramento.
Philly would have an incentive to be better than the Kings in 2017 so they could complete the swap!
3) The Kings traded their 2018 1st round pick to Philly (protected for selections 1-10). If the pick isn't conveyed in 2018--it becomes an UNPROTECTED 2019 1ST ROUND PICK.
If the Kings trade Cousins now, they could compete with Philly & Brooklyn for worst record in 2016, 2017, & 2018. By 2019, they'd have a team likely comprised of 3 lottery picks (of their own), plus whatever we send them in the Cousins trade.
Hopefully by then they'd at least have a Minnesota-esque team put together for the 2019 season, and be ready to surrender their 2019 1st round pick
