What do you think about this...?

I like the idea, because no one said engine must be an actual thruster or exhaust. Vide: Honor Harrington series.

Warshawski sails represent.

Ship doesn't really look FL-ish enough for me, but it might be the time where disco decides to start redefining the FL 'style' a bit with changes. It could be nice to see ingame.

That gave me idea - it could be neat Omega-origin Zoner or civilian ship design, replaced with that bigass core known from the Rheinland shipline.

You know, sort of what Unioners did to CTE.

That fighter profile reminds me a lot of the Sunrider. Except probably even thinner from the front at least when I look at the wings.
But I'm seeing some cool stuff here, to be quite honest.

Also what Fluff said, could actually work like that. To me it would at least give some variety in here again.
