One could get an appropriate mask off a monochrome set (there are some that are dead ringers for the internal 15GP22 mask) and select an inline gun that would fit inside the factory mounts and fill the added mask. It would be a lot of work to make such a modification in a reversible manner, but I'm convinced it is possible. Given the time and money many collectors have spent on rebuild work for only glimpses of shaky success, I feel this is probably much less difficult of an undertaking to the right people.
If I had a $200 15GP22 based set with a bad or missing CRT you can bet that would be my course of action till a better alternative became feasible.

I think I'd give it a try too. I'm not suggesting modifying a perfectly good set, but let's face it, good tubes are very hard to find. I'd rather see an early set making a picture, even if it required a little "cheating," then having it sitting in the corner of someone's basement because parts were not available. It would be important to save and document original components just in case putting it back to original equipment ever became possible. I doubt it would be easy, but if anyone ever attempts it, I hope they are willing to share information about how they went about it.
