Radio Shack SWR meter

I just posted a question on the RS SWR meter and the thread
dissapeared.

Here is my question again. Is there some way of modifying
the Radio Shack SWR meter (27MHZ) to make it work in the
aircraft radio range (120MHZ)?

I am not asking if I should use it or not but what circuit
modification can be done so it centers in the aircraft VHF
frequencies. SWR circuitry is usually simple and the RS
SWR meter already's got the meter and knobs. Anybody's
done that already?
