Got a cheap Heller 1:72 Mirage IVA. Feel the itch to covert it into a heavy interceptor, probably with a new nose and bigger radome. Operator candidates are France (AFAIK, this was even a real world plan), a USAF successor to the DeltaDart, or something Swedish. A Tu-28 alternative is also an option, though... so many ideas, gotta let the creative dust settle for a while.
