If you're looking for carpet-like plants that will do well in alkaline water, Echinodorus tenellus (Pygmy Chain Sword) would be a good bet.
Anubias will tolerate 8.0 well.
Come to think of it, the only thing you might have a real problem with would be softwater species, i.e. Tonina and some Ludwigia spp.. Most anything will grow in 8.0 as long as nutrient, carbon, and lighting requirements are met.
