Well, i see no problem in editing infocards of the ships to replace one name with another. And we are ain't adding much actually, nearly all these classes are already available and present but not in right order. I think its good to fix that is really broken not mentioning that it will give us some eye cookie and warm instead of fixing what is not actually broken.
Sorting ships to classes could be simply made by placing them near each others in milkshape and comparing their sizes.
