a lot of job ahead you, but I stick my thumbs.
I do not know if Creo is the best tool to handle it, but if you are going to finally select it, check below comments to help guide you through your task
in short most demanded areas -IMHO regarding Creo - from technical and skills perspective are:
1) nose part(forebody) - here big credits to Jeff4136: you are great!
