Increase Raster Extent by Adding a Row or Column of Cells for Aggregation

I am interested in running an iterative Aggregation analysis on a raster dataset over different configurations. A solution that I thought of to do this is to:

  1. Increase the raster extent by adding several rows and columns of "NULL" cells to the raster of interest
  2. Within a loop
    1. Aggregate the combined raster with larger extent to produce my first dataset
    2. Add one row or one column (increasing the extent slightly so the aggregation covers a different configuration)
    3. Aggregating the slightly larger combined raster to produce my second dataset
    4. Repeating the row/column addition and aggregation to produce the third through one-hundreth dataset

I have some ideas as to how to do this, but would greatly appreciate any advice or other ideas to achieve my goal of increasing the raster extent iteratively. Thank you!
