I would not go down that road, remember the discussion we had some time ago where the consensus was that single level/area is soo much better simpler and features friendly compared to hierarchical models.
And anyways the main FIB consumer are the customer VPN prefixes.

Agreed, less costs and less things to break.

Well you could build the L2 rings as 10GE -so you'd have 2x10GE cust-agg in and 2x10GE out to MPLS.

If I understood our product guy well the statement from Juniper was that there are no slightest plans for PBB-EVPN. 
Which was a true wtf moment for me as one would think they'd like the box to be a competition for ASR9k.
