is there any guitar out there that sounds like a stratocaster and is less than 25.5" in scale
Yup. You can get a strat in a shorter scale, for that matter. 25", 24.75", even less.
You can get an approximation.
Out of production, but still available: the 24.75" scale Godin SD family.
Well, I used to use a 66' Fender Mustang (24" Scale) when playing Ritchie Blackmore stuff, worked GREAT for Highway Star, but that's in the bridge position only, and switching pickups is not that easy if you're not used to the Mustang's switching system
