I don't think that's a good idea. "Mobile first" doesn't mean "mobile everywhere". You can use umatrix and stylus Firefox extensions to eliminate most page bloat. Firefox's reader view can give the same look to each page if that's what you want.
Destroying the open WWW for the purpose of making all websites look the same on all devices doesn't seem like a good justification.
