Trees, Shrubs and Conifers: pruning a mock orange, 0 by dathen

I have this mock orange at the corner of my house and it has gotten out of hand size-wise. I've trimmed it from the top several times (it's probably 30 years old). There are no limbs coming out from the bottom for the first 5 feet or so....bare. Am I going to have to trim it down past where the bottom branches start in order to get growth on the bottom part of the tree or will that kill it? The top branches are higher than my 2nd storey window. Thank you for any suggestions.
