No, the scenario you described is not possible.
Generally, gains and losses are added together for a particular tax year to determine your overall gain or loss for that year only. You do not have any control over choosing which tax year to report a gain. It is reported in the year the gain occurs. If you have an overall loss, then you may be able to carry some of that loss over to the following tax year. That is the only time that you can change the year in which a capital gain or loss is reported (by carrying it over).
