I really like both names on their own, but put together it looks like it should sound like “[name]Aria[/name] Mayaria”. You might actually get away from this with the alternate spelling - [name]Aria[/name] [name]Maya[/name]. I know you don’t care for that as much, but it does look better and not so rhymey. Perhaps you might want to consider combining the two names into one and adding a new mn?
One very similar name that I like is Maiara (could be pronounced may-ah-ra, or may-ra). I know of one person with this name - Maiara [name]Walsh[/name]. According to an interview she gave it is a common name in [name]Brazil[/name], (she pronounces it my-[name]AH[/name]-ta), and means “mother” or “nurse”. However I connect it (and it’s meaning) to “[name]Maia[/name]” with the added ending of “-ara”. I had wanted to use this as a middle name for my daughter, but my husband didn’t care for it, so we settled on [name]Mae[/name]. I still do love it, though.
