I wouldn't even mess with it. If you have an MTU mismatch on the
same layer-2 domain, you have a Broken Network. If you manage to
make it work with duct tape and zip ties, you're only setting
yourself up for operational pain down the road. Just put a layer-3
hop in between your standard frame and jumbo frame hosts, and you're
good to go.
The other thing people often do is block all ICMP because "ICMP is
bad" and then wonder why path MTU discovery breaks :P
