Name Creation Exercise

Thought this up as I was waking up this morning -- a relatively simple idea for name creating. Basically you take a name that already exists, and bump the letter forward or backward in the alphabet depending on if it's a vowel or consonant. I'll give some examples I thought up:

JOHN SMITH becomes:

KIJP TNESG (consonants forward, vowels backward)

That doesn't look too nice, so let's try the reverse:

HUGM RLOSJ

...well, it doesn't work with every name. ^^; Let's try a popular one from fantasy.

BILBO BAGGINS

Consonants forward, vowels backward, it's:

CEMCI CYHHEPT [Y is counted as a vowel here]

There could be something useful there. And the reverse:

ZOKZU ZEFFOMR

Take off the R and it looks pretty cool, IMO.

Bumping both types of letter in the same direction could yield some interesting results as well. What can you guys come up with?
