That being said, it's clear that people really don't like the idea of Synthesis, so I will explore other means of giving it Morning Sun / Moonlight. Maybe having both that and Recover as level-up moves is not terrible if the distance between them is enough?
In my moveset Mollux learns both Wish and Moonlight as Level Up moves, and of these, Wish is learned very early while Moonlight very late. They serve different purposes, for early game and late game healing. So I don't think adding two healing moves in the level up list is a bad idea at all.
Before you do that though, think of the competitive consequences: sun, rain and weatherless teams will all be able to pick the healing move of their preference and still tailor Mollux to their needs with whatever egg moves it gets. If you're fine with that much freedom, I'd say go for it.
