Do you have any advice as to what may happen if I advertise

This probably qualifies as a "unique routing policy" under ARIN NRPM
section 5. That allows you to get another AS number.
Why burn an ASN? There is no need. With "neighbor $FOO allowas-in",
you can even see your own prefixes.
You could also get a small block of staticly-routed IPs from your ISPs
in each location and use them to anchor a VPN (e.g. a GRE tunnel).
That'd have the effect of extending your backbone.
Another useful suggestion. Hell, don't even need GRE tunnels - who
said all your IP space had to be in your personal ASN?
