That remains to be seen. Typically all interfaces in IX peering LANs 
have the same MTU. How likely is it that a router takes the peering LAN 
address as source address for a packet too big message? Has anyone ever 
investigated the behaviour of the various router implementations?

There is a reason why IX space should not be exported, namely to 
prevent routing issues. Since eBGP learned routes are better than a 
iBGP learned routes.
