[c-nsp] eompls with different vlans at the ends

hello,

topology:
Host1 --> switches -->PE --eompls--PE <-- switches <- Host2

config PE (7604 sup 720 / IOS SRA3):
subinterface + encapulation dot1q vlan X + xconnect (MUX-UNI)

problem:
if vlan X for Host1 is different then vlan X for Host 2, on the first switch 
connected directly to PE we will have STP bloking state at VlanX.

questions:
is there a possibility to solve that, except "spann disable on vlan X" 
or "spann bpdu filter enable" on switches, or the same vlan X on both ends ? 
can i filter somehow bpdu throught the eompls tunnel ?

thank you,
liviu.
