No, I don't think so. As long as a label for a given 32/ or 128/ FEC is attached to a packet, no matter from whichever label distribution protocol this label is learnt, the packet would definitely be forwarded to the node identified by that FEC along the shortest path.
Could you give a concrete example to illustrate why the forwarding result is rather poor?
