Warning: I am not a lawyer

In short: technically CC0 may be used, but it would be confusing as ODBL would still
apply anyway.

See https://wiki.osmfoundation.org/wiki/Licence/Licence_Compatibility#CC0

"CC0 licenced material is in general compatible, however the license only extends
to material the licensor actually has rights in and specifically avoids making a
statement on the status of any third party material included."

So you could license this as CC0, but it does not mean that other limitations are
not applying (limited extraction of just some shapes from OpenStreetMap may
be doable without triggering ODBL - see
https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Substantial_-_Guideline
but such project would likely quickly pass it).

In the same way as Wikidata is CC0 but not importable into OpenStreetMap
as they include location data systematically copied from various sources,
for example Google Maps.
