I don't see why not. I like it, and there is no rule of grammar to prohibit it.
Not that you asked, but most English-speaking people would have said "beside the submarine", not "besides the submarine" to express that idea.
"Beside" (without the "s" is usually used as a literal, physical preposition of location in space that means "next to" or "by", as in "along came a spider and sat down beside her".
People normally use the word "besides" as a sort of discorse marker or clause modifying adverb meaning something like "as if those reasons weren't enough, here's another," as in "Why do you have to listen to me? Because I'm older and I'm smarter. Besides, I'm your father!" 
Spot on, Chris.
