I've just checked the drawing again. I hoped the X-29 bits would be about twice the scale or bigger than the TSR.2 bits, but it appears the X-29 are only about 1.75 times the scale of the TSR.2. I had hoped for a bigger scale to use 1/72 X-29 wings on a 1/144 TSR.2 fuselage. With the smaller wings, it would look more "bomber", rather than the "fighter" looks it has now. Some creative cutting might help with that...
Here's another one, this time with F-117 tails. These might actually look cooler on a fighter-sized X-29.
Hmmm, something for the X-Men?
