that's a real pain, especially since IXPs are the internet's MTU 
bottlenecks.

 From my point of view RFC 5963 should be updated to recommend the 
global announcement
of IX prefixes for IPv6 or - as already mentioned - an alternative would 
be to source the
ICMP messages from a public address instead.
