The way I'm thinking about it (probably very idealistic), if there is a mixture and method that I can use to mix batches of Ag-Plus with a red/green sensitizer to make it panchromatic then I would be able to mix batches and test the exposure iso for each batch (because each batch differs slightly) and dial in the necessary amount of red/green sensitizer. I'm trying to find the least complicated method of achieving a panchromatic emulsion. I guess it would be safe to assume that there is no method that isn't complicated to some degree but if there is a method that I can use which involves the least number of steps and is based solely on mixing readily available materials and based on some method of effectively testing sensitivity then that would be ideal and likely have a learning curve that I can handle.
