Hood was a death trap but the prettiest one afloat. I think that actually played into her demise. She was so stately, balanced, and pretty that she sort of became a poster child for the Royal Navy. And what good would it be to have your poster child in drydock for a few years, with her appearance being changed? What signal does that send? So she was left to fight in her largely original fit, incredibly inadequate even for the engagements likely when she was built, much less 20 years later.
Just my theory! I love the Hood. I think she was the ship of ships as far as looks go.
After the retrofit, she still would have been a fine looking ship. She just would have been a better looking ship all around. Decent armour. Better range.Better AA armament. Faster. Her ass wouldn't have been dragging through the water in every wave.
As the Hood would have looked after her rebuild:
