As for OP, one could think of adding an evasion stat, but it would need an accuracy one to boot, and they shouldn't be EV/IVvable for obvious reasons. But we kinda already have those, albeit hidden and equal for each pokèmon (there are moves that raise/lower evasion after all) so the only effect would be specializing some pokèmon in evading and others in "sniping". Which would be cool, admittedly, but only if done well (and it wouldn't).
