You need to speak to someone who knows how to design bikes, but a CAAD 12 with 37c tyres will handle differently to a CAAD 12 with 25c tyres, so just copying the geometry may not give you the result you were hoping for.
This is a concern. I going to have a conversation with a local framebuilder about the geometry.
