i'd recco 48 hours with 3 water changes minimum. and a lot of water to meat ratio on the soak.I would try it! Soak for at least 24 hours. Definitely go Rueben vibe! Probably be better if you cooked and then topped a burger, but seems worth a try to me.
That looks good!I had one many many years ago in Cleveland.
I thought I saw a recipe somewhere on a BBQ site and found it.
