No. An end system who only has IPv6 addresses has no way to access
IPv4-only content, regardless of whether the IPv6 address is
constructed within 2002::/16.
(and it's a bit of a stretch to imagine an end-system that has IPv4
close enough for a 6to4 prefix to be constructed, but far enough away
for it not also to have an IPv4 address)
