Thanks for your suggestions.
I'm pretty sure that we cannot have different layerheights for parts of the model other than for adaptive layerheigths. But I'll have to check that for the team. But I guess you can test your 0.3mm gap for sure if you change the overall layerheight to 0.15 because than you'll get 2 layers distance.
The problem in this case would be that the first layer printed atop the support would have to "fall" twice its layer height. A .15mm layer taking up a .3mm gap would probably give you a similarly low-quality surface as a .2mm layer taking up a .4mm gap, albeit on a smaller scale.

Would you mind sharing a picture of what you would like to see happen to the model?
Is it similar to make overhang printable where it changes to model?Or is it similar to conical support where it changes the support?
It would change the model, and the resulting support would also be different. Consider a 10x10x10mm cube floating 10mm above the built platform. If it is printed atop a support with a .4mm z-gap, then you end up with a 10x10x10.4 cube. (I tested this using cura's "standard quality" profile, the cube actually ended up 10x10x10.57, perhaps due to irregularities in the support surface.) If the model were to be adjusted so that it's a 10x10x9.6 mm cube, located at 10.4mm above the build platform the cube should be dimensionally accurate, in principle.
Incidentally, a variation on adaptive layer height could be used to achieve sub-layer-height dimensional accuracy for horizontal surfaces. (both upward and downward facing) Any time a horizontal surface is not at a multiple of the layer height, the height of the last few layers before that surface could be adjusted so that the surface is at exactly the correct height.
Another thought, which would really only be practical for horizontal support surfaces, might be to have the printer pause before the final layer of the support surface. Then the user could manually swap a dissolvable filament for that last layer of the support, with the printer pausing again after that part of the layer has been printed and the user swapping in the original filament. Then one could print without a z-gap (which I presume is partly the point of a dissolvable filament), at least for horizontal surfaces.
