The /24 would probably work as long as you can get your upstream to agree not to filter it - or you might just stomp on somebody else if the carrier reassigned it to someone else. Probably not a good long term plan for customer use in any case since the original carrier may reclaim them at some unpredictable point in the future.
You’re likely going to have a hard time with the /27’s since a lot of providers still filter at /24 boundaries and global visibility will probably be poor.
