That's an interesting theory, but I'm not sure I can agree with it, Marius. I think it would be highly unlikely for someone to simply drop 'were to'. After all, it's only the 'were to' part that would make 'go' more hypothetical than probable.
If someone wanted that part of the sentence to sound more hypothetical (i.e. to match the more hypothetical second part), they would probably say "If I went on bended knee..." or the full "If I were to go on bended knee...".
As Trex's sentence is written, the "If I go" part sounds like something that the speaker is looking at as a real option, and not as a strictly hypothetical one.
