I don't believe xmodem transfer have been necessary beginning with the 
Cat 3550s or there abouts.  The last xmodem I had to do was on a 2900XL 
but nothing more recent than that.  rommon should be able to do TFTP 
transfers beginning with the 3550s.

That said, I don't have an answer for your original question.  I don't 
know that a small image would be needed if the rommon can provide the 
file transfer functionality that you're needing though.
