Can I alternate the mesh surfaces in such script?

Hi,


I was wondering if I can extract the surfaces of a mesh to change it around. Particularly, I wish to change the number of edges on each surface if that is possible, hence the same sort of geometry overall out put (does not need to be exact) but a mesh of maybe consisting of hexagons? or octagons or random combination.


Another thing I wish to try but failed was to maybe create a cull pattern of the individual surfaces ( the faces of the deconstructed mesh), hence leaving empty or cut out small pieces in the overall geometry. 



Thanks very much in advance,

Cheers
