WI Epiphany Rising was successfull and Richard II was restored?

After the murder of Thomas of Woodstock 1st Duke of Gloucester in 1397, King Richard II rewarded those who had supported him against Gloucester and the Lords Appelant with a plethora of new titles.
Upon the usurpation and accession of King Henry IV in 1399, many of those titles were placed under attainder, due to the complicity of their holders in the murder of the Duke of Gloucester.

The ringleaders of the conspiracy were John Montagu 3rd Earl of Salisbury, John Holland 1st Earl of Huntigdon (formerly Duke of Exeter), Thomas Holland 3rd Earl of Kent (formerly Duke of Surrey), and Thomas le Despencer 4th Baron le Despencer (formerly Earl of Gloucester). Other members included Edward of Norwich 1st Earl of Rutland (formerly Duke of Aumale), and Ralph Lumley 1st Baron Lumley.
They hoped to seize King Henry IV during a joust tournament at Windsor, kill him, and restore Richard II to the throne. However, Edward of Norwich betrayed the conspirators to King Henry. Forewarned, Henry failed to appear at Windsor and began to raise an army in London. The conspirators fled to the western counties and raised the standard of rebellion. However, they obtained little support and were quickly apprehended by local authorities.
WI Edward of Norwich doesnt betray the other nobles and Henry IV was murdered and Richard II was restored? How is this affecting History? Could England had avoided the Wars of the Roses? Any thoughts?
 
Or the newly restored Richard II falls victim of an assassination by the late Henry's IV followers and an alternate War of Roses beggins?
