A swap is how the Celtics got the #1 pick in 2017. NY (or whoever) are more than welcome to receive a pick after the lottery for their trouble.
I'm also shooting for '27 and '29 picks from LA, but would "fall back" to '27 and '29 (super?) swaps and '28 unprotected. FWIW.
A swap is also how Chicago got the #2 pick in the 2006 draft.
