Is it possible to make my existing 6509 switch function as a 7600 router? Even if it means purchasing a new sup or other inline card.
I need certain router features, such as q-in-q tag termination.
We need to terminate q-in-q tags from wholesale fiber customers. We have a handover at one site, which I am thinking that I will q-in-q trunk over our own dark fiber using 3750E switches.
Will need to authenticate DHCP option 82;
A nice to have would be VPDN, and replace our existing LNS;
- GRE
- MPLS VPN
- OSPF
- BGP

6500 is generally MPLS ready in terms of label support, LDP support and things like VRFs for MPLS VPNs. Some features may be missing because of specific choice of software and hardware.
For example, in your configuration, you'll have very small FIB for services - you have only PFC3B which can hold 256k IPv4 prefixes, or 128k IPv6 prefixes, or half of that for MPLS VPN services (MPLS label takes two entries basically).
Second problem you may hit is the fact that while the 6748 LC you have has MPLS tagging support, it will only do 802.1q tunneling - if you need 802.1q swapping and elastic modifications/etc there is a a whole set of different restrictions (port groups) which you can start to deep dive into here:

Essentially, for 6500 to function as fully fledged metro ethernet edge you'll either need SIP linecards (SIP-200 and SIP-400) or ES/ES+ linecards, which are by itself feature-rich for services like tag swapping, services termination, QoS/HQoS etc. The "LAN cards" as they're called (WS-X6[1357]xx series) are limited in QoS and L2 manipulation flexibility.
