Thermite grenades don't "detonate" (technically speaking.)  However,  
my impression that the typical "thermite grenade" is aimed at  
destroying heavy equipment (truck engines/etc) by burning a hole  
through the metal parts, and is therefore poorly suited to  
destruction of more distributed but more sensitive material like  
paper and electronics.  It really ought to be possible to "tune" a  
safe/thermite combination to heat the contents of the safe to  
temperatures sufficient to destroy everything inside without melting  
through the safe itself (though the outside will certainly get plenty  
hot.)  My initial thought is simply to use a milder thermite or  
"gasless delay" type composition is lining for the entire safe -  
silicon/lead oxide for instance.  I would be surprised if there isn't  
something available from suitable "security" providers (thought it  
may require some interesting licensing...)
