I have a couple of varieties of these rose style azaleas, they are pretty tough. No smell though. I am not familiar with your climate, but from recent threads, it sounds a lot like mine only I get summer sooner and winter comes a lot later, lol. I would have no problem cutting it back to nothing, but that is me, and I have a bunch of these around in posts, this variety roots easily. To be safe, I don't know what size pot it is in, but you could up size the pot to give the roots some room to grow, when the roots have room the top is more likely to grow. Then when you finish enjoying the flowers cut the branches back the closest growth to the trunk. This should stimulate some growth all over. It is gonna bud some anyway, this is one of the azaleas that looses a lot of foliage in the winter, in the summer it puts on a lot. Once you get some shoots low where you want, cut back to them. Make smooth cuts and seal everything up nice when you are done. I did this with MS Paint, so don't laugh, but cut where the red lines are and remove the small growth marked in black. You don't want to have that many branches at a junction, it will make an ugly buldge.
That is the Mellow Mullet safe plan.
The "all in" plan would be to cut it to about 12 inches and go for broke, lol. I recommend you go safe and slow and watch how it responds to what you do, once you see how it responds, you will have a better idea about how to treat it. Azaleas are very predictable, they respond the same way every year.
