While I agree with the rest of the guys who posted (on the suitability of the boat), the answer to your question about concealment is another issue.
A couple of camo nets should easily (and cheaply) cover a boat that small while keeping a low profile. Drape a net over the shoulders of the shooters, and don't stand up to shoot.
(I assume you have adequately weighed the dangers of what you are planning, and have made an intelligent decision about what steps you will be taking, safety-wise, to ensure that both of you come home dry and breathing. )
Often wrong, never in doubt...
