I actually like the current Tiger Shark design. It's just the quality that bugs me. If you can remake the ship following a similar design concept but with a better quality and using the same textures as the rest of the Rheinland civilian ships, that'd be great.

As for the model you've proposed though, even though I like the general design of it, I just can't get to like those wings, and like a few people already pointed out, I also can't see it as a Rheinland type of design either.
