The only problem with your domain spells is that the spell level should match the domain level. Gentle repose isn't a first level spell and I don't think it should be a first level domain spell either. This is exactly why cure light wounds is the first domain spell on the Healing list. If you can find another first level spell that could substitute, then I would consider using your domain. Heck, you could even add homebrewed spells to this if you wanted. I'm just concerned about power balance. Also, gentle repose can only be cast on dead creatures. This would not exactly be my first pick for a domain spell.
