I think in both cases the first names being such “spiritual” word names may make [name_f]Nirvana[/name_f] a bit too much, even as a middle name, even for a Buddhist. Combined with the band, it also makes for a very fan-girly meaning.
I think [name_u]Vida[/name_u] [name_f]Oceana[/name_f] actually matches [name_u]Alma[/name_u] Rivera perfectly, giving you two spiritual, water-related names.
