Why not start with the ultimate 50s-60s-70s aircraft? Take an SR-71
and do wizard stuff to that - it would have some amazing possibilites
if it were built with everything available today. It would end up
needing docking capability for refueling from the ISS!

What modern engines would you fit to an SR-71 that would not destroy its
aerodynamic profile yet enable it to work both in the earth's atmosphere
and
outside it?

Did the original poster say I had to solve all the engineering
questions to make it work? No. It was a simple "what if", which I
answered.

I did read it as stating that major changes to the airframe design are not
allowed, only minor changes like to the size of the engine bays.
