Run on the basic DCS infared unit at the moment. I saw the Explorer unit. Only downfall I see is no control over switches. Would have to extend the push button controls lower, and wire to a bigger button to push with a stick. Or the next step with the TIU, AIU, Wifi.

Dont plan to expand. Just these to 2 setups, run one at a time.

My interpretation is the TIU-AIU approach is quite expensive - several hundred dollars - if the primary reason for upgrading is wireless control of the Ross switches.
Each AIU Switch port is basically a pair of relays. One or the other relay momentarily closes for 1/2 sec to emulate the manual button control for straight or diverge. For about $5 you can get a wireless relay as shown above; these are used for DIY garage-door projects and the like. Using a 2-button fob, and 2 wireless relays you could then control a switch.
Obviously this control method is not integrated into the DCS handheld remote. OTOH, that you thought of extending the switch wiring and pressing buttons with a stick caught my attention. That is, the "stick" is also a wireless control method that is not-integrated into the train-control remote!
