Reports on Tuesday claim founder and interim CEO Jack Dorsey is supporting plans to go back on the founding principle, enshrined since Twitter's inception back in 2006.
Re/code sources say the company's desperate efforts to stimulate user growth has led the social network to consider a drastic change in approach.
Those familiar with the matter aren't clear on how the new tweets would look, but it will apparently be different to the tools that allow users to post longer blocks of text as images.
Whether the firm will simply up the amount of characters available to users or has another solution in mind remains to be seen, but going too far risks becoming even more Facebook-like.
The company has been experimenting with ways to give users more scope to express themselves this year.
The retweet option was recently expanded to allow users to post their own comments. Twitter also dropped the 140-character limit from Direct Messages last month, which had never quite made sense in the first place.
The report says Twitter has come close to pulling the trigger on the change before, but talk of change has resurfaced with greater support in recent months.
One unnamed employee reportedly said: "People have been very precious at Twitter about what Twitter can be and how much it can be evolved. Having Jack come in and say it's okay makes all the difference in the world."
