Replacement Domes for Athearn Tank Car?

StephenK
 

I am preparing to do a model of a UP 0-50-6 tank car and am considering basing this on an Athearn blue box car. THe dome on this model is apparently too small. Does anyone make a replacement part for this? Or better yet, is there a more accurate model of this design? There is an article in the March 1999 MRR that describes a major rebuild of the dome,which I would like to avoid if possible.

Any ideas?
