Sources in the party said there was general consensus among the party leaders on the former finance minister's name for the top post.
They said majority of the BJP leaders feel that the party should form the government if invited by Lt Governor Najeeb Jung to take over the reins.
74-year-old Mukhi represents Janakpuri constituency and was elected to the assembly for seven consecutive terms.
The sources said a final decision on who will be the chief minister in case the party decides to form government will be taken by BJP Parliamentary Board.
Meanwhile, hectic consultations were held today by Home Minister Rajnath Singh with Delhi BJP chief Satish Upadhyay, Union minister Nitin Gadkari, BJP leader Prabhat Jha, who is the state in-charge in the party.
Moves in the ruling party came a day after Jung sent a report to President Pranab Mukherjee seeking permission to explore the possibilities of formation of a government by consulting the single largest party.
"The party will take a decision," the Home Minister told reporters after Gadkari, who is election in-charge of party affairs in Delhi, met him at the North Block.
