Technically polygamy is legal you just don't register your marriages, though you could still get married the eastern way, doing the ceremony and shyt but don't get the marriages registered.
I plan on having more than one wife, once my financial life changes, though this won't work with western women they are selfish and won't bother to try to understand polgyny.
Anyway western folk technically are serial polygamist as they get married multiple times after failed marriages plus they are getting married to the state once they get the certificate. Lastly most folk practice polygamy by having either multiple sex partners which can range from friends with benefits, side chicks, wife, gf or baby momma.
