Hmm, 'crush depth' and external air temp sound like good ideas to put in.
Maybe adding an EMER COOL button to the XR2 panel somewhere - lowers the hull exterior temp a bit, and significantly lowers the interior temp. Of course, since this would be LN2 or Main fuel (if cryogenic) going through cooling channels, the EMER button should only be allowed to run 2 or 3 times per flight.
As for more APU fuel/lox, you could just use sputniks velcro rockets add-on. Add a non removable drop tank to the XR2, and use your common sense as to its dimensions, weight etc. It would just be a matter of finding what propellant resource is what.
If you wanna look far into the future, a XR-# ship could reroute the cram intakes to siphon LOX and fuel out of a planets atmosphere. This is of course when orbiter can support atmospheric compositon. 2009 Edition anyone? (BTW, when is orbiter 2008 coming out?)
