  \set tieWaitForNote = ##t
or (if outside of the polyphonic construction)
  \set Staff.tieWaitForNote ##t
should help.

This can be done with
  \mergeDifferentlyHeadedOn
which merges half note heads and note heads of eighths or smaller. You 
won’t need the \shiftOnn and force-hshift anymore ;)

Maybe it would help you to read the Learning Manual. It has a very nice 
example how to deal with collisions in polyphony (section 4.5.3).
