Lorgar would definitely fight - he is the chaos gods yes man after all. The bitter brothers - Perturabo & Mortarion - would fight because they can never give up their grudges. Angron would fight - he doesn't know how to do anything else. Fulgrim has degenerated so far he is even less than Angron now - it would take Slaanesh with a pitch fork to get him moving. As for Magnus I think he may be plotting to seize Tzeench's power & godhood for himself - he is the only demon primarch who despises his patron after all.
