3-Way Combo Double Switch - any way to do using Insteon

Anyone have guidance on how to go about replacing something that requires a 3-Way Combination Double Switch with Insteon switches/inline modules? This particular switch is used to change the speed for a Whole House Fan - High/Medium/Low. Basically I'd like to be able to change the speeds automatically with Indigo based on temperatures inside the house/outside/etc .. See the attached image for the wiring details

There is a separate switch for a Timer+On/Off of the Fan. I've been able to replace the Timer+On/Off with an Insteon 15-amp keypad but not sure how to go about the 3 speed switch (BTW - pretty sure the basic Insteon ceiling fan speed controller won't suffice due to 15-amp needs). The existing 3-way switch is like the following one - https://www.homedepot.com/p/Leviton-15- ... /301446330

Another note - the Manufacturer also markets an RF controller module. However, I am not sure if this has any type of compatibility with other interface protocols in use with Indigo ( https://www.homedepot.com/p/QuietCool-W ... /309969038 ). I guess if I could control this particular RF module somehow that would be another option
