I think that the HP will be a distinctive one. The phasers will be a modest increase over the F, but perhaps with a slightly different color or texture, as well as sound. You'll note that the arrays on this ship have ribbing that runs lengthwise instead of across. So I think some kind of difference is warranted, as one is intended. As for torpedoes, I'm not sure yet. I do intend that the hull of this ship will be very sturdy.
Probably will do a custom shuttle for the ship as well.
I have started adding windows to the saucer. That should give you guys some sense of the scale of this ship.
