I have tendency to go over the top, so tell me to slow down if I get too overboard... 
actually, I was already thinking about everything that you had mentioned and more. I had an idea to document my art (scans, photos, etc.) as a sort of inventory or audit. The list is a prototype. I wanted tyo see what it could become. Such a list allows me to see what I have versus what I am missing. uggh. I am missing so much stuff. Inventory gives me a realistic viewpoint of my situation.
After looking at the first draft, I started to imagine a more robust list with all regions and searchable data. By the way, there is an actual EUR version of games. Although I cannot prove it via official data from Nintendo (they only care about new systems), I can prove it with scans and images. Even when there is an NOE, FRA, ITA, ESP, UKV and ITA release, there is still a EUR version. I guess it is for other nations within Europe that do not have a localization, as Russia, Poland, etc. I do not have alot of other content. In fact, I only have a few FRA, NOE and SCN scans. My personal list has EUR only because I do not think that I will ever acquire scans of every region. I do not have every scan of USA covers/labels.
As for TCP database, a complete list of regions will be a good idea. I will add all of the regions that you had mentioned. I will make a prototype page, then we can look at it and discuss ideas.
I am currently (for the past six hours) downloading 800x600 photos of Nipponese cartridges and saving all of the data in a text file. So much work. I am trying to fully document the SNES game releases. A global Master List. I want to atleast have photos of every game of every region. scans are a fantasy. Thanks to all of the folks here at TCP, I am able to start building a collection. I have many, many, MANY projects in my life. I have other things to purchase so buying all of the games to scan them is out of reach. I will purchase some of the games that I cannot find so that I can get manual/label and cover scans but I hope that more people share scans with us because I cannot buy every game.
Anyway, I like what you had mentioned and I will start programming it today.
I have to save and document some more Nipponese games. By the way, have you ever heard of Little Master? interesting label. I like the Kung-Fu Cat. lol. I only found a label photo. My point is that Japan has many titles that I am unaware of until now. interesting.
I will check back later. Have a great morning ...
