Silly question

With the recent changes in EU legislation with regards to insuring vintage aircraft, I was thinking that there might be an easy way around it - rather than refurbishing and "fixing" existing aircraft....why not just dig out the original building plans and build a couple from scratch? That way they are new, don't need expensive maintenance, and think of the advantages too (higher quality wood, stainless steel, etc.)
