Kpnuts, I think what the OP meant is that he tried to tweak designs and registry numbers and what not, so that they fit in better (to his taste and apparently that of mr. Thomson or Thompson) with the designs etc. shown in TOS, so with TOS-only canon so to speak. Not the canon of the whole franchise, but only of the '66-'69 series. I don't think he's in a position to add something to that canon, since you'd probably need real world time travel yourself to add something to the TOS '66-'69 canon, but he's free of course to make designs that he likes in the style of TOS.
At least, that's my interpretation of this puzzling post (the first time I read it I had no idea what it was about), but I'm sure the OP will correct me if I'm wrong here.
