Hmmm...TF30 powered F-16 also possible?
Considering the TF30's problems, why? If you have to use a lower tech engine for export, Allison's proposed afterburning TF41 makes far more sense. TF30's bypass ratio is on the high side for a good supersonic turbofan, as proved by its lengthy development.
For those wanting to do a F401-powered Tomcat, the difference in maximum diameter between the two is roughly 2.5 inches (once upon a time, long, long aga, I worked on both versions of the JTF22). I doubt this would be noticeable until you get to larger than 1/32-scale.
