How to bridge two or more dispersed vlan networks over GRE tunnel using cisco ios router?

I would like to know if any one has bridged vlans over a GRE for example on Site1 VLAN1..VLANn would appear on Site2 in the same broadcast domains VLAN1..VLANn.

the idea is to have the ieee802.1q subinterfaces on Tunnelling router on Site1,2:

(Site1.Vlan1..n)---(Local LAN SW1)---trunk---(GW Router1)----GRE over IPV4 Net----(GW Router2)---802.1q trunk---(Local LAN SW2)---(Site2.Vlan1..n)

for Site1..n:

(Siten.Vlan1..y)---(Local LAN SWn)---trunk---(GW Routern)----GRE over IPV4 Net----(GW Routern)---802.1q trunk---(Local LAN SWn)---(Siten.Vlan1..y)
