Gary,
   It is a lot of work to accurately set up a model for a given multiband
yagi.  However, hams do it all the time out of a labor of love for their own
antennas.  I am guessing that people have already set up models for those
two antennas and they would probably be willing to send them to you.  If
that is true, it's much easier to combine both antenna models into one with
whatever spacing you want between them.
