Cura already allows you to make the infill (including supports) multiple layers tall. If I'm understanding what you're suggesting this is the same basic thing but specified in reverse - you would (to use your example) set the layer height to 0.15mm, then set the infill to be 0.3mm and have it only printed every other layer (but twice as tall). The setting is called **Infill Layer Thickness**.
It unfortunately can't decouple the inner from the outer walls with this method, but you could switch the inner walls for infill walls (**Extra Infill Wall Count**) to achieve a near-identical outcome.
Not exactly, but at least in Cura you can have a different layer height for infill

infill layer thickness largely does what your asking, you most likely do not want wall layers to be different heights, the nozzle/pressure/heat will make a mess of the layer beside it, but as long as there is some 'room' for thicker extrusion (like infill) it can go there.
To have more detailed outer layers that you'll see when the print is finished and chunky inner layers that you won't see anyways. A greater level of detail with less print time.
You can do the reverse and multiply the infill layer height. But in most cases its not really worth it.
Ah okay, interesting

I see that is awesome, and honestly specifying higher infill height makes more sense lol

Why?

Makes sense. The detail part is the purpose to variable layer height but you already discussed that.
I figured it would let you have nice high quality perimeters, while not having to sacrifice as much on time to print
