Combine Chart Types in 2008

I'd like to illustrate a comparison between two products each with two values each for 5 different time periods thus incorporating a stacked clustered chart in a waterfall format.

Each total value for each time period for each product is split 2/3 v 1/3 -- stacked option
There are two products for each time period - cluster option
I'd like show Hour 1 through Hour 5 separately but as a total figure - waterfall option

Please contact me if more info is needed to assist.

Thanks in advance for your help
