Commerce Minister Nirmala Sitaraman could also be elevated as a cabinet minister, and Yashwant Sinha's son Jayant Sinha may be inducted as a junior minister to Arun Jaitley in the finance ministry.
The other probabales in Modi's team include BJP vice-president Mukhtar Naqvi and Maharashtra MP Hansraj Ahir, who is likely to be named the new coal minister with the rank of minister of state (independent charge).
Former RJD leader Ram Kripal Yadav, dalit leader Vijay Sampla from Punjab and Olympic silver medallist Rajyavardhan Rathore, a first-time MP from Rajasthan, are expected to be among the new faces in the council of ministers.
BJP MP Babul Supriyo could be the sole inductee from West Bengal.
