Modernized Coruscant-class Heavy Courier [Cancelled]

So, my gaming group will hopefully be using a Coruscant-class Heavy Courier as their escape ship and later regular mode of transportation in an original movie era time frame. Since the ship is 4000 years out of date, I need a modernized one. The original version of the ship can be found here:

and the modified and most famous variant is here:

However, there is one major problem before I get to the rest of the request. No on can agree how big the ship is. The two wookiepedia websites give lengths of 150 to 180 meters, but this ship has a crew of three or so, which does not make sense to me, given that a corellian corvette is that length and has a crew of at least one hundred. I am guessing that the ship is really about 30 or so meters long, but I am not good with that sort of thing. If whoever takes the request could try and make a guess from the pictures, and I can dig up more if necessary, and state that somewhere, I would be grateful.

So now the rest of the request. I would like the basic design to be the same, but most everything else has been upgraded in some way. The main wing should look more imperial in design, with TIE fighter like solar panels covering the surface, to deal with the increased power output. The two banks of engines at the back should be replaced with something more like the Falcon's bar engine, but keeping the same upside down V configuration. The only obvious weapon will be a quad laser mount on the front above and behind the cockpit. Less obvious will be the four photon torpedo launchers below, two to each side, and in front of the cockpit in the mandible looking area. The only other weapon will be an ion cannon turret mounted high on the back, above the engines to cover the rear. The rest of the ship should be more or less the same, just more modern in Star Wars time line looking. There are two more parts to this request. First, whatever setting the ship is placed in, could there please be some sense of scale there. Have a TIE fighter flying next to it, or some people standing near it,even just a silhouette is fine. Last, and I do not mean this to be a large thing, just a sketch of the deck plan of the ship as you have drawn it. It does not have to be detailed, just a rough shape of the interior and a few notes on dimensions or scale would be enough. If anyone thinks that is too much, it can be left out of the request. I hope this is not a too large request, or too confusing. If anyone has any questions, please ask, and thank you for taking a look.
