Wow those are good mockups already! The spines look good, but I don't like the PC template, is that fuzzy pc logo a standard? Most of my other games use the Games for windowstemplate I think that should probably be the standard for pc titles in america at least. The other games i have in DVD cases use the PC DVD template but none of these games are on DVD.
I do have all the original material, unfortunately no scanner

But that's not really a big deal since i don't like the american artwork on all four games

Yeah I was going to download Brokensword 2.5 so that's good idea!
All of mine are the american NTSC versions so the first one is just titled circle of blood and the spine is sort in an intricate gold
broken sword 2 is titled the smoking mirror they both haved virgin on the spine but neither match.
the third one has broken sword also in gold with adventure company website and adventure compnay logo
the fourth one has only a paper box and is titled secrets of the ark in america, the 3 discs are in paper sleeves and has only secrets of the ark and adventure company on the spine.
I have limited photoshop abilities so i'll do what I can.
