I was thinking It would be best to simply offset the inner walls in the xy axis, so that the printer lays down the next extrusion in the groove between two of the previous lines. This is already done with the hexagon infill pattern in orca slicer, but not yet available for inner walls. It would also be helpful to adjust extrusion to deliberately create large grooves bewteen the lines. Outer walls and cosmetic features should of course printed regularly.

The advantage to OP’s approach would be reduced complexity, less z-hopping and reduced risk of collision with already printed parts.
