A follow-up to this request:

It is much easier to accomplish when settings routes with a source
address that is a public IP like this:

ip route add default via 10.10.10.1 src 192.0.2.24

ICMP errors will then use 192.0.2.24 as the source address.

No need for a kernel patch. Thanks for all the input.
