Home Assistant Dashboard as Web Page in another Home Assistant Dashboard

I have 1 Home Assistant instance monitoring 2 locations (local and another via VPN). The problem I am running into is latency and dropped VPN links. This results in the remote location sensors not tripping automations or getting logged.

So, my thought was to create another Home Assistant Instance at the remote location and then using Webpage Card, display its Overview as a tab on the locale HA Instance.

Does this sound reasonable/doable?

I looked at the remote_homeassistant addon but that just passes all the sensors and device streams back over to the primary HA instance - which is pretty much the same as I’m doing now.

Other Alternatives?
