Weren't there other battlecruisers?

[MGCǂSpectre]

I remember a loong time ago there used to be at least another 2 battlecruiser models based on the concept and one of them even had some similarities with the SC2 battlecruiser. I'm currently looking for any of the 2 battlecruiser models to replace the SC1 beta one that got boring and I don't wanna have it anymore.

I couldn't find any among the model section and not within the threads I searched.
