Thanks for the suggestion Dave. . . I've had a little mess around following your advice and got to the point where i have all the individual faces planar (but not joined to one another). I have then had a quick look at the new angles when extruded back inwards to a point where most of the edges are close - (the new flat angles look off with regards to mating to the neighbouring shapes as expected). Am i right in assuming that if i extrude the faces back inwards to a point where the majority of edges are very close and then tweak each vert to its closest neighbour using normal mode on the tool settings, the shapes will stay flat? Will normal mode allow me to move the verts along the plane instead of bending to meet the other verts? I realise that doing this may change each individual face slightly and i dont have a problem with that at all as long as the hex's and pent's stay planar. Will this work? ? ?

Hope it makes some sense?
