This is only true for political reasons, and most ISPs will
(reluctantly) announce a subnet from a competetor for you, with any
number of caveats about actually getting it working. They'll probably
say no, but keep asking... that no just means "I've never been asked
before". As others have said -- working with anything smaller than a
/24 is going to be super painful and you're going to have to get the
"owner" of the IPs to document the fact you have their permission to
announce on another route before your backup ISP is likely to do it,
and they might ask you to renumber.

You'll still need an ASN, but that's a lot easier/cheaper than getting
an IPv4 block of your own from ARIN.
