How about using augmented diffs from Overpass API to generate data? The API seems to work great.; but since augmented diffs from Overpass API will generate the changes on the fly, the increasing server load may be a concern.

AFAIK:

* OWL generates and stores tiles as JSON for each changeset, faster to query, but extremely disk usage heavy

* Overpass API generates augmented diffs on the fly for each minutely updates (so it requires to filtered by bbox and filtered out other changesets when used), system load may be a problem

But IMHO using Overpass API is faster and easier to implement since it has already a working API and some great proof of concepts.

Working example for Overpass API:
