Yes, step on toes. However, you're trying to step on toes here. That is your goal. The question is whether it breaks the game and it does not.
The spell lists are designed primarily to give each class a feel. What you're attempting to do here is cross the feel of the wizard into cleric territory. It isn't really that hard to 'cross the beams' as it is - this is just a more efficient way of doing it.
I don't think it adds 'good flavor' to the game, so I would not be looking to add this to my setting - but if a player really wanted it I'd make it happen and would have NO balance concerns.
