I had another thought after my original reply, but for some reason I didn't send you follow-up. Have you tried not enabling EC on Cisco doing xconnect (PE) at all and simply having it just on end-nodes: A===PE1---PE2===B
This is the configuration we use. N * GigE port based xconnect on the south side of the PE router and configure the port-channel on the "ce" device. Our PEs are multi 10GE attached. This has worked very well for us. Only problem is picking up loss of link at the far end. You really have no choice but to rely on aggressive udld to pick up the circuit loss and take it out of the port-channel. But, in our case the end systems are 6500s so you can't do fast udld timers. You may have ~~ 1sec reconvergence at L3 but an L2 issue over a pw takes about 20 seconds to be picked up by udld.
