Should I try to use CC2005 or.....?

I have got a copy of FIFA 2005 and I'm trying to do some changes. But will the CC2005 work for me?

I'm planning to import the 2005 Czech League megapatch which is made by the Czech Football Federation and then make some other changes, mainly in the Swedish and English leagues, maybe some updates in the Czech League too if the imported teams are somewhat outdated.

But can I do so without having crashes in the game itself and the CC2005? The posts I read on this forum doesn't encourage me to use the CC.

Are there better ways to edit teams, kits badges and such than the CC2005?
