You'll be glad to know that some of your ideas have already been addressed
by the working group. In the near future we hope to release the CSS3
Generated and Replaced Content Module, which will include proposals very
similar to what you describe.

The module I referred to above includes an '::outside' pseudo-element
which would let you write:

   h1::outside { display: block; }
   h1 { display: inline; border: solid; }

An interesting idea. The draft doesn't have anything quite like this, but
it does have similar ideas... You could probably do the above using:

   h3:not(:last-of-type) ~ * { move-to: between; }
   h3::outside { display: block; }
   h3::outside::before { display: block; content: pending(between); }

...which would end up wrapping all the content between <h3>s into the
h3::outside::before pseudo-element. Admittedly it is a little more
complicated. :-)
