I agree that XBL2 may have been too ambitious for it's time.

I would say that the simplest thing that would be useful would be:
a) provide a bare-bones shadow DOM
b) implement something like the NodeWatcher proposal - 
http://www.w3.org/2008/webapps/wiki/MutationReplacement#NodeWatch_.28A_Microsoft_Proposal.29

These features are independently useful and would facilitate Javascript 
library solutions similar to both HTMLElement.register and XBL2.

Then step back and see what the Javascript guys do with it. The next 
step might write itself.
