I do have, languishing in a box back in Canada, a partly finished naval Apache.
Based on the Academy 1/72 kit, I planned (and partially executed) the following changes:
Gun replaced with radar dome of the sort you'd see on the SH-60 Seahawk
Fenestron tail Rotor and SH-60 style tail landing gear at a mid boom position
Penguin missiles
I think I had some Danish or Dutch navy decals set aside for it.
