Trying to force your own stats to match up with a 'normal' range is not the best way to go about improving your game. Many different styles can be successful, especially in a game like PLO.
Your best bet is to find a style that you're comfortable with and learn to master it (and just as importantly, learn to adjust appropriately to table conditions).
That being said, you should err on the tight side when it comes to playing in the blinds. Position matters a lot in this game, and it's easy to be tempted by pot odds to play a hand that can't really make the nuts.
