I would want a player to have played two seasons before being picked for the A Team tour where hopefully they would be assessed on their temperament and skills away from home. Then they would need to get into the ODI squad before Tests. About half the players that do go on the Academy tours that have sounded like very good players have just vanished back to their counties and some have even moved counties. I don't think it is a good idea to pluck someone out of county cricket straight into Tests.
Wagh, Kenway, Peng, Wood, Wallace, Kirby, Hogg, Muchall, Stevens, Newman, Napier, Tredwell, Lumb, Shafayat, Francis, Wagg, Khalid, Harrison, Powell, Gidman, Wright, Footitt are some of them.
