Nah, the clock tower is an aspect which makes the BB unique. If we bring loads of things over to the main village from the BB then it will stop being unique.
Either way, i think that army train times are fine in the main village. It's just the heroes which take too long.
If you bring over the clock, the ratio of troop train time:hero regen time would still be the same and so people would likely still complain about how much longer heroes take rather than troops.
