Lunchbox & hexagonal geometry into a closed polysurface

Hi,

Really hoping you can help on here. I have a 5 closed polysurfaces representing different areas of the sole of a shoe.

The objective is to cut hexagonal shapes into each one (some parts of the shoe should have smaller/tighter hexagonals to stiffen the 3d printed part). Aiming to get this done by increasing the geometry in the U+V channels.

The problem, it seems that lunchbox only lets you create geometry out of surfaces, which would be fine, yet the patch function creates control points outside of the surface I am trying to push hexagons onto. So when it comes to using the "Hexagon Cells" function I can't contain the hexgons within the polysurface I am tying to push them onto.
