Drake and Josh

Okay. I have done something kind of stupid with my characters.
I named them. I did not think twice about naming them and only when I was already stuck with their names I noticed:

I have a pair of brothers, even though only one of them is the main character.
His name is Joshua but everyone only calls him Josh.

Now I gave him a big brother... who is off to college and does not appear very often.
But when he appeared he needed a name and I named him Drake.

Now everytime they interact I have to write Drake and Josh in the same sentence.

The problem with that is the old nickelodeon show "Drake and Josh" even though my Drake and Josh are nothing like the Drake and Josh in the series (well except they are brothers as well...) and don't even look like them in my head I keep worrying that someone will confuse them.

How I am going to solve that?
I don't know yet but it can wait until revision.

Nearly completly unrelated to that: I am probably going to hit 28k today... or not when I come home way to late.
I will get 27k though and I will try a half an hour wordwar sometime this evening.
