I think it's too late. Should have been reviewed sooner.
If the trade was reviewed immediately/pre-draft, then both teams can build, trade, and strategize accordingly.
But seeing as no action was taken and that it is now post-draft, picks were subsequently moved and the players that were traded have been centerpieces for both teams, I don't think it warrants any change or any change would rightfully correct it.
Again, the sooner the trade are reviewed, the sooner those trades can be properly amended.
