Cervelo R5 bars & seatpost

Longest of long shots but has anyone got a Cervelo R5 on order (or know anyone that has) and wants to swap out their stock handlebars or seatpost?

I've just bought a 54cm and, without unboxing it, know ideally I'd like to swap the 25mm set back seatpost for a 0mm inline one and the 42cm (c-c) handlebars for 40cm.

They're extortionate to buy so I'll just live with them if I can't swap but you never know there might be someone out there wishing theirs came with slightly bigger parts!

Many thanks
