No. The VLAN space is chassis-global for LAN cards.

One some WAN cards I believe you can do sub-interfaces where vlans are 
re-used, but I'm not sure if that's layer2 capable, and most of the WAN 
cards are pricey and low density so probably useless for your case.

VLAN translation might be of some use to you, but you've got to be 
careful with the caveats (port groupings, limits on number of mappings)
