There are lots of possibilities on who the new warlord could be. It could be an ally of the previous warlard like Crocodile and Moriah. Could be Marco the only reason i could for these 3 is that they somehow want to get their revenge back either on WG itself (destrying WG or marine from the inside) or someone else and using WG as a backup or to hide their true intension.

I would love to see marco again but not as a warlard. Maybe he would come to the rescue when luffy is in need of help or if their is another war involving luffy. Because his ace's brother and also WB told them to PROTECT luffy
