I don't have power door locks, so I'm just brainstorming here... Take it for what it's worth.
It would be the same principal as above, but perhaps a little more complicated If you have made the mod described above, you already have one (switched) power source wired to "trick" the step control. Making the step retract with door lock activation would require a second power circuit, which would be controlled with a latching relay (like the one that controls your water pump).
When you lock the doors with the key fob, a signal is sent to activate the individual door locks. I assume this is a momentary signal (ie the door lock solenoids are not constantly powered). You could tap into the signal going to any one of the door locks and have it also activate a latching solenoid. The latching solenoid would close sending a "tricking" power signal to the step control (just like the manual switched circuit).
So, when you lock the doors with your fob the latching solenoid is activated (closes) and power is sent to step control. Step closes. When you unlock the doors with your fob the latching solenoid is again activated (opens) and cuts the power signal going to the step control. Step opens. Bob's your uncle!
