    Write a function that enhances a customer's credit risk score by activating all positive credit factors in the bank's automated loan approval system, where positive factors are represented by even-positioned bits in the binary risk score. The function should set all even-positioned bits to 1 while preserving the original values of odd-positioned bits, effectively highlighting favorable credit criteria for loan pre-qualification assessment.
