Yup. I had that moment in high school. I had a 1:48 F-14 from earlier that I wasn't happy with the paint job on, so I hacked off the engines to turn into a double-barreled arm cannon well before Michael Bay did it with Ironhide, and when I was looking at the leftover front-end stuff to see if there was anything I could do with it, I though about cutting out the cockpit bulge and linking the remaining portions of fuselage together directly, and all of a sudden I saw it. I wasn't sure what else had been used, but was pretty sure space shuttle boosters were the source of the engines. The 1:144 ones I had looked like they might be about the right size.
