Yea, but it isnt as clean and not generic. For example, I would have

I wish there was a way to fill in values in the request object, that
way I wouldnt have to change any code at all.

And with a modern servlet spec, there is! You'll still have to get the
new information to the new request somehow. Once it's there, though,
you can set up a servlet filter that builds a wrapped ServletRequest
object and adds parameters and/or request attributes. Google on servlet
filters for details.
