Is this variant of Elemental Adept for healing balanced?

I know that most healing does not work on constructs or undead in DnD 5e. However, for various reasons, I would like to subvert that. I was looking over feats to base such a subversion on and stumbled upon the Elemental Adept. Is the following feat likely to either break the game or be underpowered if I include it?

Healing Adept

Prerequisite: the Spellcasting feature and at least one healing spell

Your healing spells work on constructs and undead. In addition, if you roll to see how many hit points you can heal, you may treat any 1 on a die as a 2.

If it’s too weak, I am thinking it’s possible to modify so that it allows Raise Dead and family to resurrect an undead either as itself or as the undead it was. If it’s too strong, I was thinking of taking away the “treat any 1 on a die as a 2”, and possibly forcing you to pick if it works on constructs or on undead.
