This is not a "brandable" name. I am sorry to say that this is just a terrible name.
Just because Lyft made their name this way, does not mean it works for any other word. The major mistake you have made is thinking it's a good idea to replace a c with an h, which is silly and does not mean anything.
Lyft works becasue i and y sound exactly the same, when used in this word.
If we can substitute letters in all kinds of words and then expect people to buy those words for $x,xxx or $xx,xxx, then we can register brhnd, brhnds, and brhndable, etc., also munny, muhney, muuhney, mahney, schoes, howzes, klowthes, keykez, schuger, etc.
The list is almost endless, but its a list of worthless names that no-one will spend money on.
