Yes in the internal forum, a persons conscience then can decide for him or her self to receive or not to receive.  It is not up to the priest or Bishop, and yes the Internal Forum is in fact the most important ethical place for each of us to go.  We see the consciences of priests and bishops lacking so much when they promote banking  and sexual scandals; and when they ruin lives of Children assaulted by clerics by refusing to give them the psychological and spiritual help to recover;  and when they refuse to understand the suffering a divorce causes in men, women and families; by believing so much in their own mummified doctrine that they fail the most important of the Commandments to love God and neighbor.
