Relatively easy to fit a smaller diameter engine into the space in which a

Compressor inlet temp can be handled by water injection (Skyburner F-4 had
it, Greenameyer's F-104 was getting it). Canopy overheating is another
problem.

If you have access to AW&ST you might want to read about Rascal that
DARPA is kicking around. It's pretty interesting and it's along
similar lines.
