I would. The ship is already with a good chunck of fragmented geometry the last thing it needs is further fragmentation with plate normal mapping.
Please don't. The ship is magnificent as is already. Do the "lets detail every single pixel" mentality in the under parts and everything that is not already "plated". It's not as if the ship is anywhere near tactical feasability - I mean it has Wings! increasing its profile for better shooting at it with no clear upside to it!
Doesn't mean I don't love it. Because I do. It's beautiful.
ON WINGS: IMHO, wings have some tactical advantages.
1) They reduce the angle from which vital structures can be attacked. I mean, let's suppose that the attacking ship is over the frigate: even if it moves to the frigate's flank it won't be able to shoot directly t the frigate's main engine. Wings work like a sort of shield.
2) The wide surface of wings may be useful to dissipate the heat caused by a beam shot.
3) The fact that it would increase the profile for better shooting is a non-issue. I don't think that having wings or not would make any difference against a late 24th century targeting system, which has to fire at a 2km long thing. A WW2 gunner was able to hit a 200m target at a distance of 10 km with rough sea... manually! (i.e. without computerized firing control)
4) The frigate's bow will be aiming directly to the target for the most of time in order to fire the main weapons. The wings frontal profile is so small that becomes irrelevant. Wings would be targetable at close distance, but this a ship that is not supposed to fight at close range...
5) Wings are cool!!! That's tactical too in FS2!
