The only reason for a TO to disallow a conversation is if the deem if offensive or not apparent as what is meant to represent.
That said TOs should not wait to rule on a ship until someone brings up the issue. If they see a ship they view as problematic they should inform the owner as such and look towards getting a replacement. Just like a TO shouldn't be waiting to intercede on other rules issues he observes.
Players looking to use a converted ship should have the courtesy to clear it with the TO during registration. It is very discourteous and presumptuous to assume a clearly written rule isn't going to be applied to you.
If a model isn't recognizable as what you are playing it as, or is possibly confused with another ship you should expect TOs to enforce the conversation policy.
I haven't seen any conversions disallowed but that may very well be because the moddling rules are so strict in appearance that you don't see much beyond slight cosmetic changes that don't change the recognition of what the model is.
