I’ve got it!  

 

It’s going to be a doublet apo refractor, but convertible from an f/5 to a f/10 with an extender ala Takahashi FC-76 DCU + EX-CQ, so that it will do double duty as both an imaging and a visual scope.  As it will split in the middle to accommodate the extender, the entire setup will fit into a compact airline compatible carry-on hardcase.

 

It will have an 88mm aperture, and (surprise) a fine, very precise, single-speed focuser to improve reliability and reduce weight and complexity.  It will be called the Galaxy 500!
