Can we expand the Grafana stack....

It would be a better fit to replace promtail and the loki ingester stack with grafana agent and to add Tempo into the MLA https://grafana.com/docs/tempo/latest/grafana-agent/.

This would reduce the processing and configuration impact on the MLA stack and add a new feature for distributed tracing. I would imagine the swap wouldnt be too difficult with the MLA gateway already configured for promtail to be modified to accept the agent and then to install the tempo chart as well

Start by reviewing the MLA gateway configuration for Promtail and the current Loki ingester stack. Then examine how the Tempo chart would fit into the MLA deployment and how Grafana Agent would replace the existing components; done means the replacement is deployed and distributed tracing is available.
