Changing a transport!

I created a transport for new company codes and realized I made few errors and need to delete them. The errors are not with CoCd settings but some other imp assignments to transports which are required in my company (like tying to release date etc.). But these company codes are already in use by other modules in their configuration. Also, neither mine or any other transports have been released yet (they are modifiable). Will my deletion affect any others configuration? I want to delete the cocds, assign the deletion to the current transport. Create the company codes with same numbers again and assign them to the new transport and delete the old transport. What is your suggestion on this... Please advise!

Thanks
