Need two books to record the same Asset with different cost

Oracle 12.1.3.

My client has a requirement, they wants to maintain two different Asset books one is with standard cost of the asset and another book they have different value (standard cost + markup) for the same asset, also they need accounting for both the books remaining things are same like Life,Depreciation method,etc.

Initially thought of implementing the tax book and map it to secondary ledger however I am seeing a challenge how to upload the assets as the cost,NBV and Acc.Depreciation are different from the corporate book also suspecting when I run the mass copy every period will it create any issues to tax book balances.
