What's your rear triangle spacing? I'm guessing that it's 130mm. I think that the wider chainline for mountain bikes is to compensate for the wider 135mm dropout spacing.
Road bike octalink is different from mountain bike octalink (except XTR). So that won't work. You might try a mountain bike front derailleur to see if it will adjust outward the extra space that you need.
