I expect you can. I know you can use a routing socket to add an arp
entry for an address that is on a subnet you do have an interface on,
but pointing to some other interface, to one for which it's off-subnet.
(I know this 'cause I've done it.)
I'll try to rip out bits of that program and build something a bit like
arp(8) but for which you specify everything manually, including the
interface. I'll see what it does for stuff like your example.
