Substitute for Frozen Lima Beans

I have a chili recipe I'm wanting to try that calls for one cup of frozen lima beans (plus canned pintos and various other ingredients). Unfortunately, while I can find dried limas and possibly canned, I can't locate frozen. Is there a problem with soaking dried limas and subbing them for the frozen? Or can I soak, cook, and freeze them if they're dried and not fresh?

The only frozen bean I can be sure of finding, apart from string beans/waxed beans, are edamame.

Thanks!
