No I wouldn't expect a lower FG, since you mashed a bit high, you probably have less fermentables, thus it will probably be a higher FG then expected. Rule of thumb stuff: Higher temps = less fermentables, higher FG, maltier beer. Lower temps = more fermentables, lower FG, drier beer. This of course is assuming your yeast pitching rate is ok.
But I bet it will still be a mighty fine brew either way. Don't sweat it. I love IIPAs.
