Phil, we used the Anubias petite mostly on the side walls in the past, the larger plants blocked light and a lot of the front view making the tank window look smaller.
So smaller epiphytes were used. Java fern Windelov will be okay I think.
You can move those around pretty well on the wall though and see for yourself.
You can also think about Anubias roots coming down, as in 1-2 ft's worth.
It can look pretty good.
