Interesting thought.  Not that familiar with LACP.  I can say for sure  
that PAgP is relying on IOS's understanding of link state so until the  
interface drops you just black-hole traffic down a port-channel member  
that doesn't go anywhere.  UDLD Aggressive will yank the interface  
down and pull it from the port-channel,   _ eventually _

Does LACP do more end-to-end signalling that could help here?
