Even with Greg's extra rule, I think the game will create many passive
positions. You could restrict the switch option to non-royal pieces, so
the King could not switch (and so, couldn't easily escape eventual
attacks).
Also, check Swap Chess (www.chessvariants.com/diffmove.dir/swap.html) as a
similar CV concept.
