Do you seriously think anyone wants another sodding referendum?
This is already "another sodding referendum".
Anyway, the answer is yes. Personally, I could see the following scenario as being feasible.
The Leavers win
Boris Johnson takes over as PM
The Europeans offer us a better deal if we change our minds
Boris calls a new referendum on the terms of the better deal.
If you want to argue that we shouldn't have another referendum even with a changed situation because democracy, I can point out several precedents including this one (referendum on EEC in the 70's). Also, the Irish once had a vote and rejected one of the EU treaties and were made to vote again to get the right answer. Also, if we vote leave but the Scots as a region vote stay, we will see another Scottish independence referendum.
