I really do like
Michaela. But with all the misspellings, it does seem to have been lost as you say. I almost wonder whether people would think
Michaela is the misspelling now!
That said, I think
Michaela's a pretty name, with a nice look and sound. I also think it goes well with a lot of other names in combos and sibsets.
Of your combos, I like
Michaela Emily the best.
