Grounded plug to receptacle without ground?

So, If I had a cord with 2 hots and 1 ground, and I wanted to plug this into one of the older dryer receptacles that has 2 hots and 1 neutral, how would I go about doing this? I know that it wouldn't be up to code, but is it possible? Would it be possible to wire it to a plug that would fit the receptacle, using 10/3 SOOW the 2 hots to the 2 hots of the non grounded plug in, leave the neutral slot empty, and then take the grounded plug from the soow, and wire it elsewhere? Is there something that provides grounding that I would simply be able to screw the grounding wire from the SOOW cord into?
