My idea for the K'Vort would be more or less based on a scaled-up 
(The K'Vort is ~350+ meters in length, the K'Tinga is 232.64 meters*) K'Tinga with the wings swept forward and the "wing-root" shape altered a little bit 
(the part of the secondary hull where the neck connects into) to look better with forward swept wings 
(the forward area of the wing-root wouldn't be as far outboard as on the D-7, and the rear area would either be the same or slightly further outboard; the forward section would still be a bit further outboard than the rear area) and a modified hammerhead and bridge dome which would have cleaner lines. 
 
I think using a more shapely nacelle design somewhat like this design would be a good idea **
 
 
Though not exactly -- just more clean-cut and elegant.

* - Officially the D-7M K'Tinga is 214 meters long. However I noticed that some images which compared the D-7 and D-7M showed them to be the same size 
(sans nacelles) and the D-7 is 228.3 meters. I essentially scaled the two images to each other sans nacelles, then added the extra nacelle length from the D-7M. The length amounted to around 232.64 meters.
