Dee Lusby writes in her webpage that one should use
foundation without pronounced cell walls.

Well I made tests and to my surprise came out the following:
I added to several hives complete supers with 11 frames. Alternating foundations with the new cell geometry and foundation after the swedish model, which has cell imprints similar to what is used anywhere. A swedish, a new one, a swedish, a new one ……. all the box like this. It was used the same wax and the same cell dimensiones between 4,8 and 4,85mm.
All this with a good nectar flow.
Next day all the hives had built combs in the frames with foundation of the new geometry and the swedish ones were not built.
