It is absolutly doable. 1st you have the ability to use MQTT Plugin in octoprint to receive messages as there is an update for example. I found this much easier then doing HTTP requests in intervalls.
Then you can do HTTP requests to do gcode commands. That is much easier than doing MQTT publish because this is a bit "complicated"... was in contact with the developer of the plugin. You have to create so much topics for receive states that I stopped using this over MQTT.
Here an example what I have built so far (right now, no in use because I switched to Klipper with Fluidd).
