It's fun to dream about what pseudonym we'd use, but, for most of us, that's putting the cart before the horse. Write the book first, then worry about the name.
If a writer is using a pseudonym, it doesn't even come into play until after the writer is made an offer of representation. Once you have an agent, s/he -- and later the editor -- may have a say in the matter. (Just as they do with the title of your darling novel.) They know marketability and may not like what you've chosen and ask you to change it. In which case they'll make suggestions, usually based on your real name.
A successful formula for pseudonyms, according to the publishing world, is a first name with two syllables and a last name with one syllable. That matches your suggestion using "Leanne Wolfe," which gets my vote for a pseudonym, if you use one. (Don't choose one lightly, either. There are a lot of things to be considered when picking one.)
As a reader, I hate author names with initials. J.K. Rowling and J.A. Konrath just to name a couple. I don't hate the authors or their work, I just hate it when authors use initials instead of an actual name. To me, it sounds pretentious, like going by one name (Madonna, Cher, etc.,). But, even then, I prefer those to silly, ridiculous names like rappers have.
