A stereo recording system uses 2 mics. Usually one on the right and left. They can also be front and back of the source but it records the same sound but from different places. So it is essentially sound in 3 D. The very small delays in picking up sounds is what your ears use to locate a sound source. That and the intensity of the sound at each ear and the difference between. If a sound is on your right your right ear will hear it fist. This is what your brain uses to determine where the sound comes from. All of that 3 D is removed when there is only one mic. It is like wearing one ear plug or an eye patch on one eye. In order for us to perceive 3D we need at least 2 sensors. If you only have one sensor, or one mic you cannot figure out the 3 D, so you cannot turn a single recording device into a 3D or stereo image. The data is not sufficent.

Not possible, period. Once you compress audio down to a single mono channel, then there is no way to separate it. It's a simple math problem, when 2 things are combined and averaged together, there is no way to know what the original source was.

3 + 1 = 4

2 + 2 = 4

1 + 3 = 4

------------

? + ? = 4

You get the idea. Once you combine the channels of audio, you cannot know what the original portions were. Similarly this math problem, you cannot solve for both ?'s.

If you just want 2 speakers playing the audio, then feed the audio to both speakers! Simple.

You may need a preamp but just have both sides take from the same source.

You can have the mono track play from both the left and right speaker by simply playing it on both speakers, or if you're talking about a digital file output then you just duplicate the mono track and link the two tracks together into a stereo pair.

I suspect though that you want to add the directionality of true stereo where the left and right tracks are different. Unfortunately , if it's possible at all and I'm not sure it is, the only way to do this would involve a tremendous amount of work manually trying to pull apart the audio file and build it into a stereo pair or an expensive piece of commercial software.
