Changing classes?

Here is the situation, I have some old characters from the early beta's they where a elementalist/necro and a mesmer/monk.

I have found they have been reset to warriors, I don't want to just make new characters because I am fond of the names.

I was wondering if there was a way to change classes or just reset the character or some other solution.

Thank you for any info

You can simply delete them and remake with the same names?

That didn't occur to me, thank you I'll give it a try
