Compact Double + Mountain Casette?
I've got an amazing touring bike originally built up with Deore XT all the way around. I'm thinking about making it more road-worthy with a compact double crank... can I leave the mountain casette on there and just put a longer chain together? Any downside really?

huge jump in gears can leave you 'wandering' between gears.
front derailer is unlikely to work with the larger chainring.

You will be fine except for the front derailleur. It may be limited on its height & too wide. It may not depending on if its a clamp-on versus a braze-on. You will essentially have a triple road setup with a double crank. Franken touring bikes often mix road with mtn components.

You should take a look at SRAM Apex. It's got up to an 11-32 cassette in the back, and is not too expensive compared to other higher road groups.

I put a 12x32 cassette and LX rear derailer on my Fuji Cross with a compact crank set up front. The bike originally came with a 48/38 CX crankset. Only adjustments were a longer chain and typical new derailer set up. In my case, I did not have to move the front derailer (although as a clamp-on I could have raised it if necessary).
I rarely use the big cogs, but I use this as a commuter with a rack and having the low gears going up a hill near my house at 6:45 am can be a real nice thing some mornings. I don't race CX at all, but do take the bike into the woods. I've used the low gearing to get up some hills when I'm feeling lazy.
As AEO said, the spacing between gears takes getting used to if you are used to riding with a more typical road cassette.
