You might be able to get away with running the different instances of 
BIRD on different ports and rely on IPTables to redirect traffic to & 
from the alternate port.  Thus likely eliminating the need to patch the 
source code.

If you're doing the redirecting, I'd be more inclined to redirect to an 
alternate IP and run each BIRD instance in it's own network namespace on 
the default ports.

You may actually be able to redirect based on PBR routes and anycast the 
same IP in the network namespaces.  --  This might also allow you to 
configure the PBR such that there is a preferred network namespace / 
BIRD instance while allowing fall back to an alternate network namespace 
/ BIRD instance.
