Good idea pinsanity - A section for Game specific and another section for general use across the board that could be used on all sort of games - like mirror blades. And maybe to add to this a not seen but valuable mod like a electrical improvement mod section.
End of the day, the way I view a mod is anything that is different in looks / features from the original issue machine that makes a machine look different, and in addition improve reliability which is not necessarily seen (electrical - this dedicated section would make searching so much easier rather than a pot luck search depends on thread heading wording - rather you just browse in a dedicated category).
I did a search and found 40 odd "MODS" which gives great inspiration.
