Your plant is at least twice as large as the ones I have, Jim. I have in mind mounting my personal one on an extra-dense, extra-thick (2") slab of cork, something about 12"x18" and as you suggested, using it horizontally. I mount half my staghorns horizontally as well. I could just as easily use cedar or cypress and have beautiful plaques of both of these woods.
Can you post a good picture when yours was in bloom? Mine have not yet bloomed and I have two different pictures of what the flowers are supposed to look like.
Thanks.
