This is simple, and nothing you can't work out for yourself.
If your plane is well-maintained, flown regularly, and has no discernible fault or problem that you can think of ;
If you are carrying (and wearing, where appropriate) the requisite safety equipement (life jackets, raft, survival gear, ELTs etc etc) ;
If you have planned your route carefully and taken into account the weather, your experience (can you fly without a horizon?), fuel, diversion planning etc ;
THEN : you have done all you can to make your trip in a light single as safe as possible.
Now : do you fancy the risk or not ? There's no point asking on this forum or anywhere else ! No-one knows your character better than you. It may sound harsh, but it *really* does come down to your take on risk and reward ...
