The only cheap way to do what you want is to use some other box to
either do VLAN translation or place the traffic into EoMPLS tunnels. I
am not actually sure whether the 7600 will do routed EoMPLS with
LAN-cards, I have only tried that with a SIP-600.

ES+ will obviously do what you want as you mention, and ASR1k and ASR9k
can do the same.
