OK, let's get this straight first; I wouldn't fake hours under any circumstances whatsoever!
BUT...
I fly helicopters regularly, but need 12 hours every second year to keep my f/w PPL. With around 200 f/w hours, and lots of helicopter flying practice, I find a f/w hour every couple of months keeps me current enough that I feel safe, and those (including instructors) who've flown with me think I am. BUT it's not enough for the CAA. So I need to do 12 hours this year (and I will, I'll re-emphasise that). But if I owned my own f/w aircraft, who's to know? If I did the hours abroad, and borrowed a privately owned aircraft, who could check up? Who would even bother?
As I've already said twice, I wouldn't do it. And I'm probably not typical anyway. But for the sake of accuracy, are you really telling me it can't be done?
