Oddly enough, no, I really, really don't want to try that.You want to try getting 80 people to concentrate at the start and staring down taxi drivers, matey!
The KO for my first FNRttC was the Jubilee one to Whitstable which started on the S. bank. I do remember that, as it was a new thing, but I don't remember there being problems. The KO for a recent one this spring (Whitstable? can't remember) was from Tooley Street and although the meeting place left a bit to be desired in terms of space and shelter I don't remember the start at all which suggests it was painless.
