I think it would be best optimized to be a brick-to-brick weapon. This would make bricks merge at random with those of similar color. Any effects such as brick walls would be lost. If it were brick-to-brick, you could, say, have a 2x2 brick and a 2x6 brick put end to end. Aim at them, click them both, then right click, and it searches for a brick whose dimensions are 2x8, and preferably within the same category and subcategory in the brick menu, then it merges. If not, it tries to merge in an efficient manner.
The only concern that I have is a lot of people using this at once.
