How do I represent such a transformation? Let's say I have a 2d rectangle defined by $ [0,x_0] \times [0,y_0]$. Now lets say I cut out the middle rectangle $[\frac{1}{3} x_0, \frac{2}{3} x_0] \times [\frac{1}{3} y_0, \frac{2}{3} y_0]$. Now suppose I take the hyperreal extension of this rectangle. I then "fill" back up the middle rectangle. I increase the rectangle to $ [0,x_0 + \varepsilon] \times [0,y_0 + \varepsilon]$ where $\varepsilon \in \mathbb{R}_{\varepsilon}$ (the infinitesimals). I then cut out the analagous middle rectangle of this square. I then proceed to take the standard part of this figure. Has the standard square gotten any bigger? If I repeat this process $ N \in \mathbb{N}^*$ number of times, what can be said about the standard part? Will I see entire figure continuously increase in measure? Will I see nothing at all?   
The goal here is to make something like this process that is continuous. I want to be able to define something that increases the overall measure of the figure while still preserving the structure of the rectangle that has been cut out. 
Any thoughts?
I essentially just want to be able to increase the measure, while preserving structure.
Need more exposure on this question...

As far as looking for hyperreal approaches to constructing the carpet, which is how I understood your idea, I would suggest looking first at hyperreal approaches to constructing nowhere differentiable functions.  This was dealt recently in a paper by McGaffey here: http://arxiv.org/abs/1306.6900
