No solid loading issues, no significant amount of mixed propellant
outside the motor, no voids issues.
If they weren't miscible, there'd be a strong tendency for the liquid to
separate into two layers. If they were miscible, even somewhat, or if you
could do something like an emulsion to get them intimately mixed
temporarily regardless... then the liquid would almost certainly be an
explosive, and it might stay that way when solidified.
A report on the results would be interesting reading, provided the work
was done by someone else at least 50 miles away from me. :-)
The whole *point* of composite propellants is that the fuel and oxidizer
don't mix *too* intimately.
