Unless you need some XE specific features you can do it solely with a pair 6880s.
(Vanilla IOS 15.3 supports BGP Attribute Filter and Enhanced Attribute Error Handling features).  
Since these are going to perform L3 termination point for all the VLANs there's no need for VSS and I think the better option is to keep two separate brains.
