This is documented to work (feature called MUX-UNI) - and we've used it
in the past, and it worked just fine.  Not sure if it works with "general
L3 subifs", but it most definitely works with EoMPLS VLAN interconnects.

I have no experience with VLAN EoMPLS to an ASR901, but it works nicely
6500<->6500 and also 6500<->ASR9001 (provided the EoMPLS type is set
to "vlan" on the ASR9001).
