Thank you. Yes, a two piece stock could be done. I too have seen several different systems built on that theme. It would require a lot more work, but would be viable if a compact takedown was the goal. Since my proposition is for simply a swap barrel system for the 1920, I wouldn't consider it necessary.
The reason I'm zeroing in on the 1920 is obviously because of making use of pre-existing 99 takedown barrels. It could be done with any number of other actions, but the cost would escalate when having to procure multiple fresh barrels of the same contour.
This is just an idea I'm throwing out there for discussion at this point.
