There's no built-in support for sure. These look like Wi-Fi only devices, not Matter over Wi-Fi, and Meross does not have a documented API for any other kind of integration. (From a quick search, it also looks like the Home Assistant integration you mentioned is not part of the platform but rather custom integration.)
I did find this with a quick search, but I can't speak to anything about it: Meross
And, of course, your idea should also work!
