Just a thought Nathan but have you considered that if the mountain i.e. the cold won't come to Mohamed therefore Mohamed i.e. you might go to the mountain. Perhaps if you had a friend or acquaintance who lives in your latitude but at higher altitude[s] it might be possible to achieve your objective with this genus. Our problem with Lilium is invariably the opposite e.g. the Cardiocrinums over winter in either our garage or workshop depending on space and how many. Not having grown Lycoris I don't know how amenable it or they are to potted winter migration. Might be worth a try.
