I see 2 ideal situations
Embiid and, unless there's an excellent SG or SF prospect available, consider trading BKN's 1st for a young, promising, but affordable SG or SF... DeRozan? Gordon? Waiters? Hayward? Dragic? Stephenson? Evans? Harris? Parsons?
Wiggins-Exum-Parker and, unless there's an excellent C prospect available, consider trading BKN's 1st for a young, promising, but affordable C... Sanders? Asik?
They are gambles (there's a reason that they are affordable), but so is drafting a player out of college. Taking a flier on one of the players mentioned and a change of scenery (coaching/offense/defense) can have huge payouts.
