Yes, as a matter of fact, I have done exactly that.  It may not be easy,
but there are these things called tolerances (you know about tolerances?),
and all it takes is an out-of-tolerance slot, or out-of-tolerance key,
or (as in my case) a key which had been broken, allowing the card to 
"slip".  Also remember that the EISA key is NOT a full-height key - it
only extends half-way up the connector body.  Just a little tolerance
slippage, and you'll be able to play see-saw with your card to your 
heart's content.

Have you ever had to design a connector system?  I have, and you might
try it sometime - the constraints are much more subtle than you might
suspect...
