Can the more knowledgeable folk here recommend a thrust vectorable or already thrust vectoring pair of engines to replace the 25's Mach 3+ turbojets? Or, if possible, can the turbojets themselves be modified and made to thrust vector? Wiki says thrust vectoring is typically only used with turbofans.

Thrust vectoring is just the hydraulic adjustment of the nozzle to redirect thrust, so there's no reason it can't be used with a turbojet since the powerplant doesn't quite matter, The MiG-25 uses a variable choke nozzle, so it'll just be a case of removing those, linking them to flight control systems and installing the hydraulics to allow them a greater degree of movement.
