I've found a solution and it was easy as pie

On your steam application, go to the 'games' dropdown (not tab) and select 'add a non-steam game'
CRPG should be an option to add. Tick the checkbox next to crpg launcher, and click 'add game'. Now you can launch the crpg launcher through steam, and it'll have your steam overlay active.

We put a launcher in your launcher so you can launch while you launch.

I also renamed crpg launcher to 'Nord Invasion' so that people can actually tell when i'm playing NI versus some other module of M&B, rather handy for those steam friends who think i'm playing when I'm actually doing Napoleonic Wars or something.

That's actually a great idea.
I've also used the NI icon and i'll probably stay on this for a long while even if it's patched
Thanks for sharing!
