I'll start with the:

The Last few C-141's that went to the bone yard, were completely refurbished and just needed a little Tender Lovin Care. All it really needed was a few things to make a civilian cargo plane.
like on the KC-135R's. More power, extra lift, fuel efficiency, and the most important, comply with new lower noise laws.
off of B737, but with the exhaust routed up and not at your face, like in its current location.
r and locking system off the C-130J, so new rollers can be easily gotten when they brake, and stowed in the floor when loading rolling stock.
off of C-130J, so parts can be had easily, and with TCAS be allowed to fly on previously restricted flight paths.
. I've been told that it needed to be heavily reinforced for added safety.

With all these improvements, it could be sold as a cheap Commercial Cargo plane for small companies that can't afford larger planes but still would like to expand there customer base, and routs.
      

As soon as I figure out a way for the SR-71 to utilize Jet A-1 and run it through the skin instead of JP-7, I'll post some ideas about that.

Can I put a hot tub in a Piper cub, along with a timeshare, and bathroom. 

Oh, and i want Rockets attached to a MD530F, so me can go super fast. 

I've actually wondered if anyone has thought of putting a smallish turbine on one of the Van's RV series aircraft.  I think a RV-4 or RV-8 with a 300 hp Walther turbine would be a pretty nice performer.  There are the "Rocket conversions which put a 260 hp Lycoming and some tougher skin panels on them, so I would think it wouldn't take much to make one a turbine.

Wow, I actually took the time to Google "Turbine RV", and found a multitude of projects.  Apparently I'm not the only one with the thought.

Now that's a Super Cub.  Do you have a link to the story on that baby?

B-36 with B-2 engines in place of the props.


F-15 that turns into a robot with a superiority complex.

The B-52 comment gave me a thought.  There was talk of upgrading the Buff's engines to more powerful high bypass fans, and to reduce the number from 8 to 4.  I would also think the same could be done with the 747.  They could put just two of the engines from the 777 on a 747 with power to spare.
