muli-homing is one way to justify an ASN, "unique routing policy" is
the other.  Your directly assigned /24 could be a reason to have
a unique routing policy, especially if your upstreams are unwilling
to originate it from their ASN(s).  You may want to re-apply for an
ASN and explain that you will be announcing your directly assigned
block in section 14 of the template.
