Possible! Yet again I don't think Vader let her go. More their fight was stopped due the explosion! IIRC the creators did say they are planing Ashoka future. Will she die/live, how will it happen. But they also said that it's not going to be quick, and it will be some time before it happens.
yup snips still lives its funny she had major hate at the start dave saw the hate and made her better
