I know of a few people who have taken the body/interior and trim from the MPC kit and stuck it on the chassis and running gear of the Revell kit. Looks pretty good.
Three words of caution:
1. It's my understanding that most of the recent reissues of the '67 actually has the 1970 seats in it, which are quite different. Several resin-casting operations, including The Modelhaus have the correct seats at reasonable prices- about $3.
2. The '66 Rally I wheels are wrong for a '67. You could use the Hurst mags in the '66, though, or possibly adapt the MPC wheels.
3. The Tri-Power was last used in '66. While I wouldn't be shocked if a few '67s had that installed at the dealer, you might want to adapt the single 4-BBL '67 intake/carb/air-cleaner onto the otherwise very nice Revell engine.
But yes, the MPC kit can be built with patience and care. Think of it this way- your skills aren't there- YET. As I always used to tell my students when I taught, just because you can't do something now doesn't mean you can't learn to to do it now. This hobby is about the learning experience as much as it is anything else. That said, if you want to tackle another kit of two until you're more comfortable with this, go for it.
