No Church Fathers or early reputable sources that I am aware of.
The most prominent ancient text which considers Judas Iscariot a hero is the Gnostic Gospel of Judas. It was not written by Judas--it appears to date to the 2nd century, long after Judas Iscariot was dead.
A polite description of The Gospel of Judas would be that it is pseudepigraphal. A more blunt description would be that it is a forgery. There is no basis for concluding that it is a reliable historical document; it's origin is far more likely a creation of 2nd-century Gnostic propaganda.
The Gospel of Judas claims that Judas was the sole disciple faithful enough to receive greater teachings from Jesus and to carry out the dreadful but necessary mission of handing Jesus over to the authorities. This view of Judas gained some attention when the a copy of the long-lost Gospel of Judas was rediscovered in the 20th century.
Prior to the rediscovery of the Gospel of Judas, there had been some periodic efforts in the last few centuries to recast Judas as a hero; I am unaware of any ancient basis for these views.

The Evidence of Early, Well-Placed Sources
If we accept the traditional authorship of the 1st & 4th Gospels (I do, see my thoughts here & here), then we have two very relevant early documents written by people who were there and knew Judas personally.
Matthew states:
The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! It had been good for that man if he had not been born (Matthew 26:24).
And John quotes Jesus referring to Judas thus:
none of them is lost, but the son of perdition (John 17:12)
Matthew & John were in a pretty good position to know what they were talking about, and they do not cast Judas in a positive light. They do not appear to believe Judas in on-track for salvation.
