Apologies for a very late reply. I forgot my account details and it took me some months to remember/recover them.
You spoke of a model, there is one already. The Empire Titan has two Lions propelling the carriage.
Is it possible to "copy" and shrink the Lion model from the titan and make it a single unit?
If it's not, please forgine my ignorance, I know nothing about modding and this was just a thought that occurred to me long time ago.
