You are doing well, my friend. I would not try building Rome in a single day, however. For most of what is on your list you will have to "learn" the logo you seek, then get a bit creative with either Photo Shop or GIMP to manipulate pieces into a reconstruction of the original logo as I and many others have had to do (hence why, in many cases, some opt to go for the system photos instead of the actual logo). Like you, I much prefer the original logos as they are almost as much a part of the history of the system as the systems themselves and if you end up reading some of the descriptions of the logos and their evolution for each, you may find a deeper appreciation of the system. I have to ask one question: Do you intend to emulate them all? To avoid being overwhelmed and stressed, you may want to start with those you are already emulating and intend to in the very near future.
