GrapesJS integration

Dear nextcloud community,

Had the Idea of integrating GrapesJS into nextcloud as an app.
So far i created a github repository with a skeleton app. Check it out if you like:

My ultimate goal would be an easy system for creating webpages and hosting them under new subdomains (comparable to wordpress). What would be the best way to approach this? Has someone already tried? Should I contact the GrapesJS community first? All suggestions are welcome.
