Espace 3.5 V6 Auto to Manual conversion

Hi new to the site and I am probably going to ask the impossible! I have a 2004 Grand Espace 3.5 V6 and it is a beautiful rare car but I hate the auto gearbox. Can a manual conversion be done? Yes I know it involves not only the box but the pedals, master cylinder, ecu etc but was wondering if there are parts out there that would fit. Yes its a lot of labour too but would be carried out by myself and my mechanic friend. I think the car would be awesome with a manual box. I hope my first post tests you all!! Cheers
