Even Wycliffe, a young man at the time of the plague, did his most important work in the decades after.
The labour shortage resulting from the plague did, of course, do much to bid up wages and improve the lot of peasants over the next three centuries or so. But the tradition of religious freedom would require another 500 years or so to take firm root in the Old World, with America getting ahead of the curve by a century or so.
It was thus inevitable that these early reformers got caught up in politics, either as an initial means of self-defense in cases like Wycliffe and Luther or as an eventual means to trade places with their former oppressors as in cases like Cromwell and Calvin.
The publication of the King James Bible overshadowed any of these men as a means to bring about the concept of religious freedom and establish it as a cornerstone concept in our new nation.
The Lollard movement was associated with the instability of society. Which is the major reason why there was no English translation of the Bible after the invention of the printing press. There was in every other nation. It was more an anti-clerical movement than a religious reform, and since Huss was influenced by it, that made the Crown even more intolerant. Henry V was a heretic hunter for that reason.But the Reformation had nothing to do with relgious freedom as we understand it. That is not what Luther meant by Christian liberty. Cathokics tried to tar Luthger as a Hussite, but he kept his skirts clean by using the protection of his Prince. Luther was strictly an Establishmentarian.
