change permalinks???

ok, I have my permalinks set up to display the category, then post_id

/%category%/%post_id%

Is there a way to change add characters to the post_id, or to actually change the starting number of all post id’s?

Basically, what I want to do is to have a longer post_id. For example, my site is new, so only a few posts. therefore, one of my post id’s is 6….just 6. That’s lame. I want it to always be a 10 digit number, something like 0000000006, or something to that effect. any thoughts?
