If the primary and secondary uplink peer with each other, and the primary
accepts the /48 from the secondary (which would be a good thing to do),
you are always reachable as long as the aggregate is up - the aggregate 
will draw the traffic "near to" the primary uplink, and at some point,
it will hit a router that will also know the /48, and send the packets
to the secondary uplink.

As I said: we do this with customers, and it works better than the
currently available alternatives.  (It's not perfect, no.)

Not to people that have no default and decide to filter your more-specific
route, yes.
