My Grandma had those! She also had the three way version with space for meat, taters, and green beans.
Exactly my thought.
I cut the whizzer cone from my visaton FR10-8.
The paper is quite fibrous, so I added some PVA glue, let it dry and made another clean cut:
And here are the responses, before and after cutting;
the whizzer cone version is slightly worse on axis above 10 kHz, but it makes the 60° off-axis response slightly smoother.
Add back phase-plug.... Much off-axis splash/interference come from cone direct as well as bounce -- what I learned playing with LS50 Meta.
I compared three models of 4".
Two of them have withers, but I don't feel any disadvantages.

30 degree curve above 10khz less output
60 degree curve lower highs less output
on axis more output but less linear
Nice to see it measured but I won't cut the whizzer off.
Its already only a small whizzer.
I do aluminium foil tweak, also recommendable.
One time puzzlecoat or Lts50 will do a bit, too.
The whizzer alone can be made stiffer with hair spray liquor.
I won't treat the cone with hair liquor, it becomes stiffer but breaks up more in resonances. Already tried that.
But it works if treated mit alu foil then

As best i can tell, the same. Coating with this is smiliar in. concept to Freedom’s Al foil.

Visaton B80 and B100 measure well.
I would use them with my aluminium foil tweak.
If no tweaks included I prefer polypropylene or glass fiber cones.
this one is a JVC 8cm driver, I got 50 pairs of them with plastic enclosure for 2.5 euro each.
