Here is an off the wall thought. If you can't drill then get a 1/8" diamond bit for a dremel. Grind a hole in the middle of the pin. Then get a steel pop rivet and some JB weld. Insert the rivet along with a little and I mean a little JB weld into the hole. (Do not glue the dowel pin to the crank) Then if possible use the pop rivet tool to just expand the rivet at bit do not pop it. This is the reason for a steel rivet. Once the jb weld has set attach a vise grip or some other gripping tool to the shaft of the pin and hopefully pull it out. If the pin breaks it should drill out and you can try again. If the pin is not very deep and you can get a hole completely through you could get a pop rivet long enough to get to the other end.
Doesn't look like fun in any case. The above might not appeal to you but shows there may be options that just haven't been thought of.
