In an academic sense, no, revising the Bible is not heresy (though some branches of Christianity will call you a heretic for it anyhow). Every time one sect or another of Christianity wants to put out a new translation, they will also consider some revisions based on things like newly discovered manuscripts or breakthroughs in ancient linguistics.
That was not what Mr. Schlafly was doing, though. He was taking an already existing English translation of the Bible and rewording it to suit his politics. As such, yes, it would definitely be considered heresy by some people. In fact, his harshest critics were other conservative Christians, especially those with actual academic credentials in the field of Biblical Studies.
