Is it a necessity to terminate the layer 3 at the edge? You could get a 10Gbps switch and move it all back to a central location where you have your high end routers. It would then be terminated as a VLAN and be a router on a stick kind of topology. Could be a cheaper way to do it without taking MPLS all the way out to the edge.
As Tim said above, I too was thinking about the Juniper ACX. The 5048/5096 model could suit your needs. They are primarily designed as layer 1(TDM)/2 backhaul devices and i'm not sure they can do a full table. They do have full JunOS MPLS features. Could be a way to use MPLS-TE to move the layer 2 back to a core location and terminate later 3 there. Would give you some flexibility over just doing ethernet stuff as I mentioned in the first paragraph.
