New Years Corrin Healer Build?

I currently have a New Years Corrin built to be a defensive archer counter; he has Hama Ya+ (+Def), Rally Def/Res, Moonbow, Attack Def +2, Bowbreaker 3, and Spur Def/Res 2. I use him as a team bulk buffer.

Do you guys think it'd be viable to run a set with Breath of Life 3 and maybe some other healer getup? Just looking for some thoughts.
