The azaleas are not going to spread themselves around and naturalize so don't wait for that to happen. I would make the points that they are easily re-shaped to just about anything that you wish, and they are pretty easy to move (probably during the cold season or in conjunction with serious trimming ... which you might do immediately after bloom.) They would look better together, not overhanging the end of the building and trimmed to look as if they are "aware" of the windows of which they are in front.

Gardening is quite often the collecting and arranging of plants -- which can be lovely and adorable -- without the regard for their effect on the larger space, i.e., a garden might not especially "care" about the presence of a building or a street, etc. ... whereas landscaping is cognizant of the larger space and demands plantings and arranging that enhance the overall space and the elements within it. Here, I think you are gardening your home, not landscaping it. It's possible that if it were landscaped instead, it could bring the overall picture together better. For example, while the plants in the circular bed are pretty, is that bed placed and planted so as to enhance the entrance as much as possible? I don't think it is. To enhance an entrance (an opening that one must go to in order to enter a building) it's more likely that plants AROUND the opening will enhance it, rather than plants directly in front of it. If you think about how you might enhance an eye with make-up, you're not going to plaster liner and shadow directly on your cornea or the whites of your eyes. Instead you'd put it AROUND the outside of eye to make it appear larger, fuller and prettier. It's not much different than that.
