I think this is impossible, for the following reason: The ROMs in a
mega-ST have a standard pinout. All pins are used on these ROMs. 
An EPROM needs an extra pin (Vpp) in order to program it, and with
this standard pinout, there is just no spare pin left for this function.
So I am afraid you will not be able to find EPROMs which can be used as
an equivalent for the 2-ROM set.
