If that happens we won't get it this year, which isn't that bad. It would be nice to have it so they can trade one of the picks, either that pick or the Heat pick, and keep the other but we really don't need need both this year, especially if they can't package them in a trade and select players for themselves. Most thought it wouldn't convey this year when the trade was originally made also, so if it doesn't convey it's not that big of a deal. It's only been in play for the last few weeks with the Bucks being a lot worse than anticipated.
It may hold more value in a trade as a future pick rather than trying to find a team interested in taking both picks.
If the Suns land at #4 and try to trade up for #1 or #2, a package with the Suns #4 pick, the #15 or #16 pick from Miami, and a future pick from the Bucks may be more attractive than the #4, #15, and #16 all this year. Who knows. Not many teams are ready to take on 3 rookies, especially 3 first round picks with all of them being that high also. It's one thing if a late 1st rounder doesn't pan out #28 or #29 but teams selecting in the teens expect to get a player that can actually produce.
