Not a very good idea.

Even if you use ceramic packages, this high a temperature will severely
weaken the wire bonds to the die pads.  You might get a few devices that
still work, but you wouldn't have any idea for how long.

Better to buy a cheap sunlamp.  OR...I wonder how many thousand of the little
critters would fit into a tanning bed.  Get together with all your friends
and buy an hour session at the local electric beach....;-) ;-)
