I cna get small headstones.  I live four doors from a stone-cutter.
There's a placeb where they discard their damaged work, and the 
locals are permitted to collect it (we use it in our gardens).
Right now there's one with a name, dates and some scrollwork,
about 3x2x2 feet, in granite.

It would be mind-numbing to find a tombstone neatly placed on 
the bottom.  But the stone would be small and dense.
