Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In a real life environment, spatial data is highly sked. In general, there are two kinds of skews in spatial data. One is the placement skew and the other is the area skew.  introduces methods and the characteristics of estimating the accurate result sizes of the multiway join for the area sked spatial data. Especially, this paper describes the number and sort of the statistics which the optimizer should keep in order to calculate the multi-way join result size. Experimental results show our approach generally provides accurate estimation for the multi-way join for the area sked spatial data.
