Phonetic Development
Development Stages √MŌ > moltha- [mōltā-] > [molta] > [moltʰa-] > [molθa-]
Long vowels before clusters shortened at various times, first in Common Eldarin, so I don’t think the ū would stay long for long enough to participate in ō > ū
The most likely development path to me is mōltā- > molta- > moltʰa- > molθa-
