I doubt it. I don't think you could get enough thread into the roll pin, 
and any more pressure from the inside just makes the pin grip the sides of 
the hole harder. I tried to look up Rockwell hardness figures for these 
pins and for cobalt drill bits. The bits are (according to the single 
source I found) indeed harder than the roll pins so, as Keith suggested, it 
may actually be possible to drill them out. It would certainly impress me 
if it worked.
