cloki can be used to read metrics out of any CH table so it should work fine.

we also just introduced experimental support for ingesting OTLP/ZIPKIN spans and a tempo-compatible API in cloki, looking for testers to validate this feature:

Internally trace spans are stored as tagged JSON logs, meaning they are available from both Loki and Tempo APIs and can be used from pretty much any visualization, too!

Those are 2 separate projects and they don't work together. I still did not have a chance to try loki / tempo so can't say how well they work in practice...
