One wall of my family room has a soffit with a duct within it running the length of the room; another wall has a soffit with a duct about 1/5 the length of the room. The plan is to install crown along both, but I'm concerned that securing it only to the roof joists won't work, and I'm concerned about leakage if I start punching nailgun holes into the ducting itself.

Moving the ductwork is not an option.

One thing I'm pondering is to somehow secure a 1/2" thick wood frame around the soffit to provide a secure nailing surface, attaching it at the ceiling and to the studs beneath the soffit, but that's an ugly solution and I'm hoping for something smarter.

(Skipping the crown would be inconvenient, as I'm planning to use the crown to hide the speaker wire for the home theater setup.)

Thoughts or suggestions would be very much appreciated!

Here is an option for you.
Attach a strip of wood up in the corner with liquid nail. Allow it to set up for at least a day. Once this is set up you attach the crown by nailing into the strip at a upward angle.
Apply a few small dabs of liquid nail on the bottom edge also.
I would use a brad nailer if possible. I usually shoot a few shorter brads on the bottom into the drywall to hold it till the liquid nail sets up.
To figure how big of a piece, place a piece of crown on a flat surface exactly how it will sit on the wall. This will allow you to see how much room there is behind the crown.
There should be some kind of a header piece at the top of the header. Use a small drill bit and explore at the top and see whats in there.
Hope this helps
