Cool tricks! _Delcorners is excellent!
I don't use the same exactly way than your (not rebuild here) but use your _Delcorners and ExplodeMove of Michael for more possibilities of placement variations ;)

_Voronoi >> Kill Points >> > Select All>> Planar >> Trim >> Select Edges >> Copy Move them somewhere >> Join >> Delcorners>>ExplodeMove

Works like a charm!
All fantasy are possible! :)
Voronoi, Delcorners, Flow

... "voronoi" shoe :-)
