If it works for you it works for you. In reality, it doesn't matter how long or short the stick is. If you want the blade to sit completely flat, simply close the blade face. Rarely, if ever, do you skate with the blade perfectly vertical. Generally, if you have the blade vertical, you're just making things harder on yourself in terms catching passes and stickhandling, etc.
In general, you just have to worry about if you're comfortable adjusting your hand placement, so that it allows the stick to sit in position that allows you to do what you need. I'm 5'5 I use lie 5 and lie 6 sitcks. Depending on how I feel, I'll tweak the heights, regardless of lie, so they're somewhere between my collarbone and just below my chin, which is between 50" and 52". When I'm using a shorter stick, my body positioning adjusts in different ways. My hands get closer together, my knees bend a little more, and the general height where my hands sit is a bit lower, which I'm fine with. When the stick is a bit longer, the opposite adjustment happens.
I remember a while back someone posted a pic of a Crosby pro stock stick. It was 54" in height. Crosby is 5'11- 6"0.
