There a few that pop into my head ( in no season order )Absolutely.
Besides Winston - I can't think of any iconic walkers from the last few seasons. Ideas?
Teddy Bear Girl
Metal head ( i think it was the epusode where Daryl "rescues" Dwight and his chick at their first meeting )
Spike head ( Jadis arena )
"grown into tree" walker
and a few random would do, for kind of "balance" on the shelfs
