If you can live with very little variety, I'd suggest a diet mainly consisting of oatmeal, chicken breasts, and protein shakes(obviously multivitamins and fish oil caps, etc...also).

I also think it's very possible; the last semester I was at Mizzou I was in a dorm with an evening dessert type service, so I ended every night with some huge chocochip cookies and raspberry smoothies. I went from being about 155 up to 185-190, but I also didnt work out the last 8-10 weeks of the sem. I had the weight off by early spring after cycling 200+ miles per week(my usual routine that I skimped on that sem) without any attention at all to diet.

Also, I'd warn against not eating for 5 hours prior to bedtime. You have the right idea down, but if you're lifting 5-6 days/week, you really need to be taking in at least 1g of protein per pound of body weight. So figure 200g/day spread out over 5-6 meals; you'll be fine snacking on some beef jerky or having a chicken breast in the evening, but giving yourself 2-3 hours to digest should be ok(5hrs seems a bit excessive). Also, look into the merits of drinking a protein shake(I mix all of mine with water) close to bed time. You body recovers at rest and it needs protein to repair the muscle you damage by lifting.

Just my two cents.
