Hi Albin,

No -- but there are regular feature requests around making repeaters
more flexible.  I hope I can enhance this for 8.4 (or 9.0.)

You can cook something from `org-after-todo-state-change-hook'.

Put the repeat value in a property, decrease it each time a task is
done until the repeater value is 0.  Displaying the repeater value can
be done in column mode.

That's for the first part of this feature -- the one with blocking
TODOs, see `org-blocker-hook' and `org-trigger-hook'.  Not sure it
will help though.

See also the manual on adding properties (i.e. `org-entry-put') and
hacking Org in general.

HTH,
