It's certainly possible to do. Public recursive DNS isn't that big of a spec that you can't have two independent teams doing it, and mandate they do things differently when possible. Run the two /24s on different ASNs, too.
I've had sales teams pitch me on their authoritative DNS service running heterogenously, although I guessing both partitions gathered config from a single place, but we didn't get that far in the potential customer pipeline.
Of course, just because it's possible doesn't mean they're likely to do it.
