Most of the enzymes your body uses to digest, come from the pancreas. That is past the stomach.

If you have a poor stomach lining and take enzymes (proteases would be in them), they could digest your stomach!

I wouldn't do it.

People with gastroparesis are sometimes given erythromycin or metformin to stimulate parestalsis. Metformin stimulates serotonin 4 receptors in the gut and moves things along for some people. The erythromycin dose is lower than the antibiotic dose.
This also moves things along. But these do not work for everyone. I would search the net for gastroparesis solutions.
The recalled drug Propulsid was very good for this problem, but it is only available now by emergency request from your doctor.
I'd discuss this with your doctor to see what could be done for you.

Sometimes people get spasms of the pylorus. When that clamps down food cannot leave the stomach either. So it would be a good idea to see if you have that problem causing your issues. If so using an anticholinergic like Levsin or Bentyl, would help relieve that spasm.
