If you can locate them, try Saururus cernuus & chinensis (Lizard's tail). I've grown both and they're attractive and very adaptable. Neither minds having their feet wet and the emerse growth is very sturdy. I'd bet either sp. would adapt to being tied in place with a bit of long fiber sphagnum over the rhizomes. Their performance is often challenging when grown submerse.
Another garden plant in two variations is Houttuynia cordata and it's colorful variegated cultivar, 'Chameleon.' They're both quite happy with wet/damp feet and the leaves are waxy and tolerant to less than optimum humidity. It's a vigorous species, many would call the green form weedy and invasive. However, I have a hunch it would do very well as a semi-epiphyte. A rhizome covering of long fiber peat or coco fiber wouldn't go wrong. Keep your scissors handy.😊
I like the scape's look & can't help but to think you could make some kuhlii loaches very happy & safe and perhaps, reproductive. Enjoy your lovely tank.
