The options I can see with CRT mounting on this cabinet are: . . . . .

Somehow modify 19" mask to accept 16" tube.

I think you can have it both ways:

Do no damage to the B&W cabinet.

If you still have the CRT bracket that was on this set when Harry Poster had it:

Since the prototype apparently has no mounting brackets, simply slide it into the cabinet with the original 19 B&W inch mask in place (or possibly a reproduction mask not so thick. You might have to fabricate a removable wooden "shelf" to raise the chassis to match the apparently higher positioned CRT in the B&W cabinet.)

It is my theory that the RCA prototype cabinets were made with oversize masks to accommodate multiple test chassis, and the front support bracket on the chassis was actually designed to be visible.

I know it is risky to assume color from a B&W photograph, but look closely at this B&W photo of an RCA color prototype from nearly the same era as your monitor:

Or this earlier color photo with the front of the TV is in deep shadow. Note the apparent double masks:

Or this RCA prototype, which is labeled a converter, but looks like it has a tuner:
