My skillset is native iOS apps so it'd be going against my strengths to make a PWA. Plus i'm skeptical of their usability. Having said all that: I mulled it over overnight, and i could use an extra private S3 bucket as the 'backend' for my app, therefore having both desktop and mobile versions with the same 'drafts' prior to publishing. That could really work I think, however it's more work than i was thinking of doing.
