It should be, if you know how to print things like that, but I don't 
Here's some code I wrote a while ago to modify the Sweave formats in a 
much simpler way:

% This removes the extra spacing after code and output chunks in Sweave,
% but keeps the spacing around the whole block.

% We want to avoid having examples switch us to an italic font shape.

Presumably some combination of \renewenvironment, \fvset (which sets 
fancyvrb parameters), or \DefineVerbatimEnvironment (a fancyvrb command) 
should do what you want.
