I'm not a fan of the 'convertible' metaphor, UDP would be better equated to driving at 100mph on a 55mph TCP road.
You might get there safely with no harm at twice the TCP speed... or you might lose some parts or you may never arrive.
That said the old battle.net online and Quake/Unreal multiplayer system was a widespread implementation of UDP transport with reliability checks. Whenever your UDP stream desynced the game clock accelerated replaying the buffered moves back to back until you were back in sync.
