Within ESS, you've got the ess-thread-eval (similar to
ess-chunk-eval), so the guts for cross-chunk evals are there, so the
next part would be as you say, making C-c C-r SWeave-aware.

An simpler alternative to code would be to allow one to
eval-chunk-and-step, stepping through chunks, similar to C-c C-n for
stepping through lines.  Would this solve the basic problem?  3 x (2
or 3 keystrokes) for 3 chunks.

I can't imagine an evaluation which would cross chunks but use only
part of chunks (this suggests bad programming design to me), but
perhaps you (or others) have an example of when this functionality
would be useful?  (i.e. actual regions to eval which cross code-chunk
boundaries but contain 1 or 2 incomplete code-chunks?).
