Why is it so high? Cabomba palaeformis, bacopa, crypts and sags could work. I am not sure about the pair of rotalas and telanthera cardinalis. The pH of my different tanks goes from 6.2 to 7.6. But never above those numbers. Some plants can adjust to different set of parameters but I have no experience with high pH tanks. You can always try though. Btw, these plants require medium light ( hairgrass is for high light or very shallow tanks). Crypts are low light and bacopa also work for low light tanks.
