You'll be fine - many many people knit this way, a combination of eastern and western styles. Just knit into the leg closest to the tip of the needle and the sts will be untwisted. The only thing in following a pattern is that you'll need to swap the decreases so they lean the correct way. Do a k2tog tbl for the ssk, and ssk where the pattern says k2tog.
Continental isn't necessarily faster because it's continental, it depends very much on the individual knitter and how productive their movements are. If you look at the youtube links I posted for english/throwing as well as loads of others there, you may find a style that's better for you and easier on your wrist without trying to learn a whole new style which is going to take time to get better at.
