My suggestion is to take the second approach you outlined but modify it 
slightly.

That way, the conflict between the 'connected' FTE introduced by 
ifconfig'ing the interface and the pre-existing FTE for that network 
prefix, may be resolved in a manner which doesn't break current 
consumers of the routing code, and leaves the way open to do multipath 
later w/o problems.
