Fair points. ^_^Nosepass would be an okay user of magic bounce since it can actually switch into dwebble and take it out. It can also wall parafusion krow to hell and back. However, Natu has access to Roost which gives it a much longer life span and can wall fighting-types and more importantly grass-types including the spore users and ferroseed. Basically I think Natu and Nosepass would work very differently and fit different teams better. I don't think Nosepass would be massively useful though without any form of recovery.
Maybe Natu and Nosepass could work together to form a status blocking core. Nosepass could deal with Natu's issues and Natu is resistant to Nosepass's Grass weakness, 4x resistant to Nosepass's Fighting weakness, and is immune to Nosepass's Ground weakness. While Natu's ability to have instant recovery with Roost (as well as temporary removal of Flying's weaknesses) can be greatly beneficial to its longevity, it is still very frail and dies to Krow and Missy both in one hit even when at full health. Nosepass does get Pain Split, and while not as reliable as Roost, it can somewhat mitigate the damage taken from switching into Krow's Brave Bird, among other things. It's also notable that Nosepass is immune to Sandstorm, whereas Natu is not. In LC, where HP stats range in the 20s, this can go a long way. Due to Natu's frailty, as well as my other aforementioned ideas and points, I'm fairly confident that Nosepass could make a greater impact than Natu as a Magic Bouncer, despite Natu having a more reliable form of recovery. I think it could make the meta shift a little more away from Krow and provide more balance.
EDIT: Nosepass also gets that 50% Special Defense boost in Sand, facilitating its longevity and status blocking power even more. This is notable for taking Missy's HP Fighting.
