Nope, sorry. Unity in name will follow from actual unity in belief. It does no good to attempt to "patch over" serious differences with band aids like clinging to the same "name" and avoiding modifiers.
Denominations happened for a reason and they are not all "personal preference" reasons. There are very real differences in belief among the various denominations. Only when this is recognized can the differences try to be resolved. Pretending differences don't matter and papaering over them with verbal obfuscation just doesn't cut it.
