Yes and yes.  I have carried 4 bicycles on my Paulchen rack many times
without incident.  The biggest problems are arranging the bikes so that
the handlebars, pedals, etc. nest together well, and with four bikes on
the back, forget about raising the hatch!

My older model Paulchen rack came with a set of extension bars and two
extra bike mounts so there are four of the trombone style bike holders on
my rack.

Best wishes,
