I tend to think that X11 over serial would be nothing short of nightmarish.
I ran X over an ISDN 64K link with 19.2Kbps backup for years in the
late 80s/early 90s, and it was pleasantly usable enough to be my daily
remote work access. Admittedly, Framemaker was a bit of a pig over
it, and we weren't web browsing pages filled with 500KB of JS and
images.
