I do not understand you...
If you remove the VLAN tags then how would your switch (or any other
network device) know where/whom the packets belonging to?!?
There "must" be an untagged VLAN in your network... So every untagged
packet will go that way... Every tagged packet will go to its own network...
You signal with the VLAN tag that you want to sent a packet to a network...
But maybe I am wrong... :D
