Can I use Thanos Query Front to Proxy Prometheus

[zxhdaniel]

In my company, My upstream department writes data to influxdb. I want to have a global read view exposed to Grafana.
Metrics data is stored in influxdb but not oss. Since Prometheus supports multiple remote readers, I think it can replace Thanos Query. Furthermore, I want to use Thanos Query Front to speed up my query to Prometheus. Finally I got this architecture. I have tested this architecture. Is it any problem? I worry about that I may miss something.

For the question from the discussion title, yes you can use QF to proxy prometheus.
