A meeting of the state BJP's core committee here last evening dwelt on a set of possible scenarios including the interim polls.
The current assembly has its term till mid-2019.
"The meeting discussed political situation in case Sena is'nt a part of the ruling dispensation," a BJP source said.
The feasibility of going for snap polls was discussed, the source told PTI.
There was unanimity over acting against the Sena's "nuisance", including the negative comments in that party's mouthpiece 'Saamana', the source said.

There was also a discussion on weaning some MLAs away from other parties and getting them re-elected on BJP symbol, the source said.
Chief Minister Devendra Fadnavis was among the leaders who attended the meeting, held at the official residence of Revenue Minister Chandrakant Patil.
In 2014 assembly polls, the BJP and the Shiv Sena had contested the polls separately. The BJP, which emerged as the single largest party, then formed a minority government with outside support of the NCP.
Despite being an ally of the BJP in Maharashtra and at the Centre, Sena kept up its stinging attack on the government's policies and even taunted Prime Minister Narendra Modi.
The Sena-BJP relations took a worse turn in recent civic polls, which they fought separately, taking tenaciously on each other.

Meanwhile, a BJP minister in the state said on the condition of anonymity that the party was confident of winning a comfortable majority if snap polls were held.
"Two options were discussed (at yesterday's meeting), one was increasing our numbers in by-elections, and plan B was to go for a mid-term poll," the minister said.
Another BJP minister said the core committee asked the legislators to take up developmental work in their constituencies on war-footing and be ready to face the electorate anytime.
A Shiv Sena leader, on the other hand, termed all this as kite-flying.
