As far as I am aware, the Vista 128's only support zone expanders over the VPLEX Bus. This solution you are looking for as far as I am aware is not possible with your particular panel without tapping into the VPLEX bus. The 128 does not support a standard 4219
Wired Zone Expander.
If you want to add RFX to your panel and monitor the RFX that is possible, just add the radio if you don't have it (a lot of times these are in existing keypads already) and add some RF type zones with their serial numbers.
In all of these instances, you will NOT be emulating a zone expander, because you cannot on a 128.
