I've finally cracked this nut, courtesy of this article
http://www.aoakley.com/articles/2016-12-29-raspberry-pi-retropie-pixel-desktop.php

In a nutshell:

Step 1: install ttyecho
curl -O "http://aoakley.com/articles/artifacts/retropie-pixel/ttyecho" &&
sudo mv ttyecho /usr/local/sbin && sudo chmod 755 /usr/local/sbin/ttyecho
&& sudo chown root.root /usr/local/sbin/ttyecho
Step 2: modify the theme (in my case, .mythtv/themes/defaultmenu/library.xml
) with the following:
 <button>
        <type>GAME</type>
        <text>Emulation Station</text>
        <action>EXEC `sudo su -c "systemctl stop lightdm ; ttyecho -n
/dev/tty1 \"emulationstation ; sudo systemctl start lightdm\""`</action>
     </button>

Now my wife can play Donkey Kong 2 and satisfy her Diddy Kong cravings!
