A good point, but I would bet that your highest efficiency of explosion
would occur when mixing similar masses of similar atomic weights.  My
guess is that forcible (probably implosion based, or possibly E-field based
combination of ionized samples) combination of similar mass and
composition samples would be most likely too cause an explosion of a
nuclear sort rather than a giant firework or fairly slow-spreading FAE-type
effect.
