Why not use KiCAD internal units ? Any necessary geometric calculation can be 
implemented in compiled _pcbnew.so
Also we can look onto Cython…

As Jean-Pierre Charras wrote in thread nearly, board names for cooper layers may 
vary:
brd = pcbnew
pcb = brd.GetBoard()
>>> pcb.SetLayerName(0, 'Top')
True
>>> pcb.SetLayerName(31, 'Bottom')
True
>>> pcb.SetLayerName(32, 'BottomGlue')
False
>>>

Thank you for cooperate… :)
