I don’t think this is a good idea. We’ll run into a situation with many different not-dom guis having the same set of problems that existing not-dom guis had for all these years. Think gnome-like drama for the half of the internet. Dom/css is no doubt a mountain of something stinky, but at least it is a slow moving standard and never had any politics or bdfl opinions involved. Also it has a set of features (e.g. accessibility, ad blocking) which would be hard to implement everywhere in the same way. Maybe something more low-level than dom but still integratable with higher-level apis and features could be built into a new browser paradigm.
