Nah, you need more than afterburners. The SR-71 had some very advanced nozzle inlets for its engines which allowed the plane to move and bounce the supersonic shockwave around in the engine inlet to generate extra compression and to keep the incoming air from just building up and flowing around the engine instead of through it. If you took a F22 and pushed it up to those speeds, it would flame out and stop working long before it got near the SR-71's too speed.
