The 1X2 is rated at 15KV PIV. So, it would break down. They're probably running the 16GP4 at 10KV or less, maybe 9.5KV. That would still cause the 1X2 to break down.
The 1X2-A, and 1X2-B are rated at 20KV PIV, the 1X2-C is rated at 22KV PIV.
If you can find a 1X2-A,B, or C then it would probably work without the modifications you made.

Just a little ditty for the "outside the box thinking" department , i wonder if at some point the flyback could've been replaced with one putting out higher HV, intended to drive a larger CRT.
