Just noticed you said 'track crank'--not too familiar with them--are they set up where you can only mount ONE ring?
It looks like I could do this. The double-ring crank I replaced seems to have one chainring mounted on the inner-side of the spider and one on the outer-side. It looks like perhaps if I used longer 'bolts' (I'm not sure what these are called on the crank; they look similar to rivets) I should be able to do this. I'm not sure; here are some photographs if they are any help:
