The Pegasus will have some battle damage by default as she had scorch marks and patched hull plates by the time we see her join the fleet. Besides, clean hulls are boring these days.
I normally avoid fully-canon ships for the reason that making them accurate is often a chore but I do sometimes make exceptions. The Peg is one of my favorite designs, as you can tell by the ridiculous level of detail I put into the frakkin' thing.
I wouldn't place any bets on a Galactica getting made as it would be too much of a hassle to texture and/or model all those ribs. Besides, Coxxon's version is fine and it runs smooth if the texture size is reduced and the gun batteries are left out.
