I'm not sure if this is even possible using standard protocols.  Bridging is 
for Ethernet; PPP is not Ethernet.  So this would require some sort of 
nonstandard Ethernet-over-PPP encapsulation protocol, and would only make 
sense if the PPP devices at both ends of the link talked this protocol.

This sounds like a job for something outside the kernel, e.g. OpenVPN as 
suggested or a simpler Ethernet-over-IP tunnelling app.
