Thank you for the suggestion CC. I had already thought about that and only after analyzing several stuffs, I decided to settle with BBpress. One, it’s lightweight and shares WP core as you mentioned. It also shares the WP userbase, under one roof. Maintenance is quite easy in a way. Besides, Discourse uses a lot of resources, which I can’t afford yet. It’s pretty neat and modern, but 1GB of RAM is way too pricey to have. So in the end, BBpress wins in several scenarios.
