Sure, but you'd need a custom shader (one that doesn't use the normal TCs
for the normal map).
Or redo your texture mapping... the "more space for more detail" isn't
that relevant for normal maps; they don't have to have the same density
everywhere (but obviously you'll also get less normal mapping detail in the
lower density mapping). The mirroring is the bigger issue.
But there are also workarounds for mirroring. I think duplicating the
vertices on a split border are one way ... tho not sure. Google a bit
around.
