Good idea in theory but the B internationals were phased out because the club managers didn't want to release players for them, and it's hard enough to get players to show up for full international friendlies as it is, so B matches were really turning into C or D matches that didn't demonstrate much of use.
I think has managed to try out a few prospects in friendlies by the way, but he does seem rather set in his ways when it comes to some regular picks. For me, scoring a hat trick against Gibraltar still doesn't justify the inclusion of Fletcher as first choice striker when his strike rate for club and country has been terrible in recent years. It's not just that he doesn't score many, but that he fluffs so many perfectly good chances you'd expect to see put away at a high level.
