Is this doable on a CNC mill?

The following link shows a real car rim and a 1:8 model of it:

The objective is to make a 1:43 model of the rim and I am wondering if
this is doable on my mini mill. My concern is not with the general
cylindrical shape, but with those curved slots with *angled* fins
going around the perimeter. I do not not if it critical for the fins
to actually angle (like a fan or propeller for directing air through
the hub).

My question is: is this doable and how could it be done?

I figure at that scale, the slots are only about 0.9 mm at the widest
points. Realizing that even that size could not duplicate the finer
detail, are end mills even available at that size? Would it even be
practical to use tools that small or would deflection and breakage
just make it impractical to make these parts?

I know this is borderline for the list, and it may be off topic, so please, let's discuss the design of the machine for such a part.

Would I need a 3 axis mill, or 4 axes ? 5 axes ???

Would it be easier or better to try to move the head or the part ?

Is milling the best way ? Is there other technologies that would offer something better ?

Also, would you please comment on what advantages a moving head might offer over a rotary table ?

Please try to keep the topic within the topic of machine design and builing and not on how to use the machine. (ie, please don't comment on feed rates and such)

TIA,
Adrian
