No. 2nds are next to worthless in terms of trade value. They're the kinds of things you get tossed into deals that are otherwise close to even or when you're flipping a guy just to get him off your roster.
There's rumors that Orlando wants to move up into the top 4 from the 5th spot and that doing so would likely cost them that 5th pick and the 8th pick which they got in a trade with Chicago.
To be honest, if the Magic offered 5 & 8 to the Raptors for 4th, I'd consider it. I'm not necessarily advocating taking it, but a combo of, say, Scottie Barnes and one of Sengun, Wagner, Mitchell, Giddey or Jalen Johnson might be enough of an alternative to give you pause while you ponder.
I think Siakam is much more valuable than Wiggins so I wouldn't want to do that. Wiggins remains a somewhat one-dimensional volume scorer seemingly without the head or heart to maximize the value out of his defensive tool set. Siakam is also a volume scorer (exasperated by the fact that he's the #1 scorer for the Raptors while Wiggins is at best 3rd) but when he's locked in he's also a terrific defender 2 through 5.
Of secondary consideration is that most of the prospects in the 6-12 range on a lot of boards are also mid-sized perimeter wing guys so you're acquiring wiggins and then he coupled with Anunoby/Trent/whoever potentially chokes away the path to a rotation spot for that pick.
