You can force this to work if using the ignition in channel 5 by doing a Pmix to negate the Gear switch.
You would need to do a Pmix with Gear as Master and Gear as Slave at negative -100%, leaving the switch assignment ON.

Now if you go into your second Pmix and make Master Flap (CH6) and Slave Gear at positive +100%, and leave the channel assignment ON, your Flap switch should activate channel 5.
