All perfect praise be to Allah, The Lord of The Worlds, and may His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.

If a Muslim intended Ihram for Umrah during the days of Hajj, he is permitted to combine Hajj with it to perform Qiraan type of Hajj so long as he didn`t offer the arrival circumambulation.

However, if he intended to perform Ifraad type, then he isn`t permitted to combine it with an Umrah to become Qiraan type of Hajj. And Allah Knows Best.
