nanuchan,
If this is what you want to do, might as well have that ceremony before coming to the USA. Just be certain that having the ceremony does not create a marriage recognized by the authorities.
He can possibly leave and come back within the 90 days if you do not first get married in the USA, but he must get back and get married to you within the 90 days. And he must convince the consulate to re-issue the visa, which they may or may not be willing to do.
