A Complex Problem..

Ok then, i hope this makes sense to you all..
I d'loaded disk 1 of echelons Grandia 2... i fixed the zap magic problem easy... BUT! disk 2 has been taken down from the website, so i was wondering this.
I know where to get the hooligans version of grandia 2... now can i take the needed fmv files from that rip (using iso-buster) and put them into echelons disk 1 rip... then delete the disk 1 fmv's (so hopefully the disk will be an ok size)
If this is ok, then can somebody please help me by telling me what files in the hooligans release are the ones i need for echelons disk 2... and what files do i need to delete from echelons disk 1?
thanks everyone, cos im sure someone will know the answer
