I don't think it can work.  The other direction needs proper ARPing to
get the correct destination MACs into the packets...

It might work if the box in question claims to be a "serial half-bridge"
(like "the remote end of a Cisco<->Cisco bridge over a G.703 line")...  
but even in that case, the local router would have to do briding, or 
something like "route-bridge IP on serials" (which is not there, as far 
as I know).
