Do away with cabin baggage altogether and issue a standard size bag(smallish)to each passenger at check in and say this is all you are allowed to take on board, please put any personal items you want in the cabin in here. Make it an international requirement.
That seems a strange thing to want to do. Most passengers will already have a perfectly serviceable bag available at home which they will pack there. If you want to issue them with a new bag at the airport what do they use to take their belongings to the airport? The selection of suitable travelling bags is a personal choice, they may not like the style you have selected for them: different travellers will have different requirements. Regular travellers will end up with many they bags they have no use for. Good news for bag makers, bad news for the environment. Does not seem a very well thought out plan..... Just seems away of putting up costs for no real benefit..... Can guess who will end up paying for the bags !!!
Think it much better to leave travellers to select their own bag/luggage.....seems to have worked well over the years.
