So you want to print the bulk of the print normal but exterior perimiters only in a lower layer height? I don't think any slicers do that but I don't see any reason why it wouldn't work and potentially give a higher resolution exterior finish in less time than just lowering the layer height for the whole print.
edit: just saw that someone already pointed out that cura does essentially this but the infill being the focus, and that you already saw it.
