I think you would have to advertise your /29 prefix via both ISP A and
ISP B, and have/accept default routes with different weights to both
ISPs. That way, you would have both inbound and outbound failover.

I'm Not sure how you would have inbound failover without peering with
both providers.

Is this /29 part of a larger IP block 'owned by' ISP A?
