I'm experimenting with 1/72 plastics to replace the blocks.
Here's a group of painted Greeks with thin magnets glued to their bases, attached to a metal base stand. The base has been spray painted with a color very close to the yellow of the C&C:A mounted board.
The idea is it will be much easier to move them as a group (even easier than 4 separate blocks) and figures are easily removed as casualties are taken.
I'll post some more pics in the near future, but for now I think I like the way it is going...
