The above suggestion makes a lot of sense for the No1. At most two barrels say a hunting and a target, stainless or blued (taped for a scope-a picatany rail would be too ugly), composite or walnut stock. Offering a threaded barrel option might make sense as well. This would make the No1 a viable long term rifle architecture. That would result in 4 barrels (either could be threaded) two receivers, and two stocks (maybe add a PRC stock?). Do any rifle would have 8 variants plus the chosen caliber. (A blued receiver with a stainless barrel would not make sense!)
