Got this from one of Unrealentgaming's What-If battle videos -

Team 1 is Broly, Paikuhan, Bojack, SSJ3 Vegeta, and Pure/Kid Buu.
Team 2 is Super Perfect Cell, Super 13, SSJ3 Goku, Grade 3 Trunks, and Cooler.
Broly loses to Super Perfect Cell, Paikuhan one shots SP Cell (as evident in the episode Warriors of The Dead) as well as Bojack, absolutely destroys Super 13, who is stated to be weaker than 16 in the Daizenshuu. Paikuhan then gets defeated by SSJ3 Goku.
SSJ3 Goku, depending on how much trouble Paikuhan gives him, defeats or draws SSJ3 Vegeta due to being stronger and having more experience with SSJ3. If Goku loses, SSJ3 Vegeta slaughters Grade 3 Trunks and Cooler and team 1 will win.
If Goku wins, he gets defeated by Pure Buu due to energy and stamina loss from his fights with Paikuhan and SSJ3 Vegeta.
Team 1 wins in my opinion.
