I do plenty of small batch all grain brewing and I've NEVER found that to be the case....Beer making is all a matter of scale, and it is easy to scale a recipe up and down, with no change in the flavor of the beer due to the "each little grain affecting taste.
Nor if you scale, do the ibus get affected.
a one gallon batch would have 1/5 the grainbil/hopbilll of a 5 gallon batch , 2.5 gallon has 1/2 of a 5 gallon recipe and a 10 gallon has TWICE that of the 5 gallon...simple as that.
That's way often microbreweries will provide their recipes to homebrewers in % like "80% pilsner, 5% 2-row, 10% munich."
ReeseAllen does that cooler have a spigot on it? If not how do you intend to drain the mashtun and then sparge it.
I use an unmodified 2 gallon cooler for a lot of my small btaches it holds up to 4 pounds of grain.
I just us a folding steamer in the bottom along with a grain bag. Just break off or unscrew the center post.
One of these, it helps to lift the grain bag above the spigot to keep the drainig from getting stuck.
I posted a lot of info in the mr beer thread that you may find helpful.

THe basic brewing radio guys are big fans of tiny batch brewing...3/4 gallon (1 6pack) in a 1 gallon winejug fermenter.
They demo the 6-pack IPA here
and they also have done barleywines as well.
