Answer

There is actually a long discussion if it is proper to begin with to divide the reading.(See פסקי תשובות סי' תרצב הערה 4)
In any case, some major Poskim allowed doing so, especially when a need arises to do so. However, all readers should be present for the berachot and reading.
To answer your question, , the first reader should say the first berachot and the second reader may say the Beracha at the end.
(סי' תרצ"ב, משנ"ב)

May you have a Happy Purim
