Stacked bar Chart Formatting

I am working on a stacked bar chart that will display project forecasts for a 12 month period. There are multiple projects that are stacked together.... I have this setup and working great, however my boss would like the display weighted so the largest value is at the bottom of each bar working up through smaller and smaller values.

This is easy if Project A > Project B > Project C, etc as I can just sort the date before charting the results. The problem occurs when Project A has a larger forecast for January, but Project B has a higher forecast in February.

I know this is probably breaking the rules as the data series's are "crossing" - instead of each having the same color order (red - green - blue - yellow) there is the possibility that the colors would be swapped up (red - blue - yellow - green)

I know this is strictly a visual thing to make finding the largest monthly forecast easier -

This can be a "native" solution, or a solution requiring macro;s - I am very comfortable with Macros, somewhat comfortable with charting, but I have never really had the need to combine the 2...

I have toyed with pie charts, donut charts, etc, and I can get what I need, but the data is not quite as easy visually to interpret. If you have any suggestions on another chart type that might suite my needs I am open to suggestions

Using Excel 2003 (I know it is dated, but our company is slow on the upgrade path...)

Thanks in advance for any advice or comments.
