I have a utility that I wrote some time ago which will rearrange the
data and address lines on a ROM image any way you like - it's
a command line utility, and you simply specify as command options
the order in which you want the output address and data lines to be
arranged. It reads Intel or Motorola HEX download format files, however
it only knows about the 16 bit address format, so it is limited to an
image size of 64k or less. If you think this might work for you, contact
me (via link on my web page) with a valid email address and I will
send it to you. [It's runs under DOS or Windows]
