I think somebody posted something similar in another thread, but I was thinking about a following trade:
1) Kemba, Smart, Thompson + 2 fillers (preferably G.Williams and Edwards) and a handful of picks and swaps for Westbrook and Beal.
OR
2) Siakam + OG for the same package as above minus Smart, if Raptors decided to rebuild.
It works in the trade machine, but I doubt it would work in real life

I also think I like the second option more because of the fit around Jays, but would be happy with either.
