I was toying around with this also. That yellow fin tuna shape is hard as heck to work with. Anyway, here is a rough idea (certainly not a finished one) I had for the top of a simple rectangular shaped cake. Maybe others can work something off it.
I was thinking of doing the fishing poles in full purple and gold with maybe "LSU" written on each of them toward the bottom by the reel. Image: http://i.imm.io/13ddQ.png
