I actually very much like your intention, as this is the brand of cricket I want to see. But you are assuming that just by bringing in youth and giving them the license, the problem will be magically solved as if that is all that it takes. If only things were that simple...
Pakistan's batting woes aren't JUST an intent/license issue, but more so they are a skill issue. To go at a high SR vs world-class bowling, you need world class skills and technical expertise similar to those possessed by players in top-tier teams.
In every sport, aggressive technique is an extension of defensive technique. Harry Brooks, Warner, and Alex Hales, all have great basics. At international stage, our kids will get exposed to the best of the best who will come with specific plans targeted towards their weaknesses.
The part that you are completely ignoring again and again is that Khusdil, Asif, Ifti, Haider, and Haris were absolute monsters in domestic T20 tournament in 2020-2021, then why do they look like fish out of water in the international stage? The answer is Skill-gaps. Do you think they don't want to play at 150+ SR lol? They are trying their best but they just don't have the game for it today. Their shot range is limited for power hitting (mid-wicket). They don't know how to use the crease well. They cant pick googlies. They cant play short-pitch. They can't pick slower deliveries. They are all waiting for "balls in their area", which hardly comes in international stage as you are not facing Amir Yamin, you are facing Wood, Boult, Starc, etc.
They need to focus on building great basics, 360 degree shot range, fitness and strength training, using the crease, competitive age group, exposure to A teams etc. Without targeted grass-root development like Eng did in 2015-2017, exposing these youngsters to this plan is like feeding lamb to lions. When this crop fails, 2 years later folks will have a list of youngsters who do well in 2024 national t20...rinse repeat.
