I think JKR is having fun with the conventions of the genre here. 
Why should it be only the villains who come up with needlessly 
elaborate plans?

But I suppose Sirius' idea was that he would be able to elude  
Voldemort's people for a long time and they would waste  time 
and energy searching for him. We don't know what happens to 
the Secret if the Secret-Keeper is killed. Does that break the 
spell? If so, Sirius may have simply thought that he would be 
killed instantly if discovered.  The real Secret Keeper would still 
be safe and Dumbledore could arrange for another decoy.

Tabouli asked about wizard Muggle marriages:
>>How do such couples meet, and how do they overcome the 
cultural differences?  How do the Muggles come to terms with 
the magical abilities of their spouses and overcome their natural 
scepticism, and what do they tell their families?<<

If most wizard families are mixed, maybe they don't shun their 
non-wizard relatives the way the Weasleys do. I can see them 
getting together for large scale family gatherings (weddings and 
such) at which there would also be unrelated friends from the 
Muggle world. The oddity wouldn't be mentioned in casual 
conversation...like Uncle Max who gets invited to everything 
'cause everybody loves him even though they all know  he's a 
bookie.  Also, wizards do frequent places like King's Cross and 
Charing Cross road, and Muggle shops occasionally. Harry runs 
into some of them as he's growing up, and Archie had to buy his 
flowered nightgown. Eyes  meet across a crowded room and 
nature does the rest...

As for how the mixed family deals with magic on a day to day 
basis...have you ever seen the old American TV sitcom 
Bewitched? You'd love it...all cross-cultural subtext, all the time.
