Of course you could, done something very similar myself a number of times. What you cannot do VFR is to have a precise schedule as Adam has here. For that you need to be able to go IFR and (at least in winter) de-iced.
Exactly my point.
And is it safe to fly for 13.5 hours out of 24 in a VFR environment in a light aircraft? And expect to be in a fit state to do business on arrival? Then to turn round and do it all again?
Sorry to sound negative but after over three decades of professional flying experience, half military and half civilian, I wouldn't personally want to rely on a light aircraft as a prime mode of transport, certainly not in the European environment.
Flight safety issues come into it, too. Press-on-itis is a dangerous thing. Putting ones self in a situation where "the show must go on" is not a recipe for reaching retirement safely.
