For this, you'd need to run a proxyarpd. I think there is such a beast
by a swedish group, but dont know if it ever was ported to 4.4-bsdish systems.

The kernel does (as for "real" routing) only implement low-level
functionality, and anything else has to be done by userland programs/daemons,
using the kernel tables as a cache.

For PPP connections, we have proxy arp in-tree (implemented in pppd, using
a routing socket to manipulate the ARP part of the kernel routing table).

Now that I think I understand more what your desire is: no, it does not belong
into the arp(4) man page, which describes kernel functionality, but into
pppd(8) [and proxyarpd(8), if we had one].
