[nsp] MPLS PE following a default ?

I have an odd question:

1. We want to provide PE type functionailty at customer sites
    by providing seperate ethernet interfaces in seperate VRFs.
    A bit like vrf lite but we need upto to ten VRFs so we want to
    deploy large boxes and configure them as PE's.

2. However we want to link these customer PEs to aggregation PEs

3. To scale the routing we want the customer PE's to just have a
    static default pointing upto the aggregation PE.

0/0----------------------><Full
Routing-------------------------------------------><-------------0/0
CustPE--------------Agg.PE---------------Core------------------------Agg.PE-
-------CustPE

My question is will the Cust PE tag the customer traffic with a label to get
the
trafic to the Agg PE by following the default router and then will the label
be popped
off and another L3 lookup be done and a new tag attached to get the traffic
to the
destination Agg PE.

Regards,
Kevin
