Quarterly depreciation TAX books setup query

Dear Gurus,

We have a requirement that the Tax books and the corporate books follow the same depreciation and prorate calendar (monthly, 12 periods). But the corporate book depreciation needs to be run monthly and the corporate books depreciate needs to be run quarterly. To achieve this, my thoughts were - to close the Tax books on a quarterly basis by running the tax book depreciation at each quarter-end. The Tax book depreciation would be run cumulatively for 3 periods, during the end of the quarter.

IS there a risk leaving the prior 2 periods open in the Tax book in each quarter when the corresponding periods are closed monthly on the corporate books?
