Kalvin,
I know what you mean about the clamshell aesthetically speaking but your bayonet is still very nice and quite scarce as it is. Keep looking, you'll be able to find one with patience. I personally like this one because of the fine detailing on the pommel and the unique blade. WKC made great products.
A grip emblem might dress it up nicely, and you really could use either emblem to finish it. I would recommend Manfred Vogel (a GD forum member) to do the replacement work, he's quite skilled and has worked on many members' daggers/bayonets.
