Like Nortexeric, I voted "other." Cooper made many important contributions to the world of shooting and served his country with honor. Cooper's concept of the "Scout rifle" is interesting from a historical perspective, but there is no reason for us to feel constrained by it, IMO. The fact that the OP has developed a very flexible concept of a scout rifle (which can include a lever action with a tubular magazine) is a good thing.
If you want a light, good handling, accurate, powerful rifle for its shooting and handling qualities, rather than for a certain "look"; decide on the purpose of the rifle, the action type (bolt, semi, lever), and cartridge. My concept and specifications are similar to those of Nortexeric. The specs would include a good quality, well balanced, short action bolt rifle with a high quality synthetic stock that fits me, medium sporter barrel, detachable box magazines (5 and 10 round), and a good trigger. 20 inch barrel. The barrel and action are made of stainless steel with a matte black coating. Cover with camo tape when needed. Mount a good quality low magnification (1.5 to 6, or 2 to 8) variable power scope with a wide field of view in the usual location. Include a detachable peep sight (or a compact red dot sight) which can be attached to the scope base when the scope is removed. The rifle I have described would be a versatile hunting and survival rifle which would work well at short range in thick cover as well as for long range shots in excess of 300 yd.
After you have perfected your design concept and defined your specifications, you will likely find that there are few if any off the rack commercial rifles which fit your specs. In my example, I would have few stainless steel bolt action rifles with a durable matte black coating and detachable 5 and 10 round box magazines available to consider. Finding a synthetic stock which will fit me would also be a big problem.
Make any modifications to my proposal or the original scout concept (or just start with a clean sheet design) which will result in a handy accurate rifle to fit your needs. Enjoy your rifle in the knowledge that Cooper would approve of your good sense and excellent intelligent choices to assemble a rifle that fits your needs best rather than following a pattern which is the product of another rifleman's concept of an ideal rifle.
