Dennis , the bow limb doesn't need to be straight and in line only the string from tip to handle to tip. I actually like an offset handle and most of my bows bend all over the place. The limb will always travel in a forward motion once it's released.
Check out the Serviceberry bow that I just posted a week ago. It has a severe jog in the upper limb and shoots like a dream. The thread is a few pages back so I'll pull it forward for you.
