Sure, it may be solution, but there is a lot of muscle memory that is bound to size of goals. If you have goalkeeper in junior league it would be very complicated to pull him up as backup to senior game. Or from lower league to upper one. All the angles and distances would need to be re-trained when switching leagues. I cannot imagine that, really. I think it would be easier to somehow limit area blocked by goalie equipment together - so if the goalie is very tall, pads would need to be either narrower or not that high to keep some max blocking area. And this is only IF we really need to do some change at all.
