Ok. It probably would have made much more sense in my original post to 
clarify that each eBGP multihop peer session is configured on separate 
loopback interfaces, apart from the ones I use internally.

Generally, I leave lo0 as-is, lo1 for internal, then configure each eBGP 
multihop peer on an incremental loopback basis thereafter.

So, in essence, I'll continue to use a loopback (separate from internal 
functions) for ebgp-multihop peers, but instead of each session having 
its own interface/IP, I'll share one for all of them.

Thanks everyone!
