So, after browsing through fontworks.co.jp, which is the site where nintendo gets their fonts from, I found out that the font used for CSP names is called Matisse, now, I haven't found a download for it, but at least I found a workaround!
The font page is available below
http://fontworks.co.jp/font/classic/matisse/UB.html (http://fontworks.co.jp/font/classic/matisse/UB.html)
If you click on it and select that grey box, you can type in any name for your character and get a preview, now, because Brawl uses low-size names, it doesn't really matter in this case! All you have to do is copy it, invert it and insert it.
Here are some examples:

This should help whoever wants to port their characters with BrawlEx and want something official-ish. Cheers!
This is great. Thanks for posting this!
Really useful stuff! Thanks bud!
Thanks! This will come in handy!
I was looking for this post. It seems the old link is dead but I think I found where the font was moved

So, Matisse Pro is close, but it's not exactly it.
You're going to want the files in this zip (http://www.mediafire.com/file/x07epb6m60161l6/Brawl_Name_Fonts.zip/file), especially the DF Min ones.
