Building your own canning recipes is generally discouraged, and if it were me I wouldn't be willing to take any risk with it. Yeah it's got vinegar (and lemon/lime juice) to bump up the acidity, and it might be OK... but is it worth it to take a chance? Instead, I'd experiment with modifying the recipe so that it cooks in the pressure canner... start with dry beans only partially cooked before canning, etc. You can probably find a good combo of raw/partially cooked ingredients that would lead to a decent taste and texture after pressure canning.
Another option would be to build at a dry mix for the recipe, and just store the basic ingredients packaged together. Dried beans, dehydrated corn, peppers, onions and seasonings, mixed together in the correct proportions and then dry-canned, vacuum-packed, or mylar/O2'd. To prepare you'd just have to add the wet ingredients (which are probably better stored separately anyway) and cook for the requisite time. Not quite as trouble-free as popping the lid of a jar and throwing it in a microwave, but the end result would likely have better taste and texture than a PC version.
Just MHO...
