LaSpino3 - This picture of Christ appearing with blood-spattered garments I have always heard preachers interpreting as the picture of Christ, the blood-sprinkled sacrifice from Calvary, stained with His own blood on our behalf.
As you have mentioned from the Isaiah 63:3 context above, the blood on Christ's garments is that from HIS ENEMIES, staining all His raiment. Picture Christ standing in a winepress, stamping grapes and getting his garments drenched from grapes spattering their juice on His clothing. Except it's not grapes He's stomping on. It's His enemies, and it is THEIR blood that He is exacting vengeance upon. "...vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge His people." (Heb. 10:30, cp Deut. 32:35)
This vengeance was going to be paid out to Christ's enemies, which in this Isaiah 63 context was HIS OWN PEOPLE, the children of Israel. In Isaiah 63:10, after recounting all the favors God had done for the house of Israel throughout their history, God says "But they rebelled, and vexed his holy Spirit: therefore HE WAS TURNED TO BE THEIR ENEMY, and he FOUGHT AGAINST THEM." It is the blood of the house of Israel that is staining Christ's garments. This happened for the first time when the Babylonians carried Judah's citizens away captive in 3 separate dispersions over several years, and finally burned the city of Jerusalem to the ground back in 586 BC. It happened again in AD 70, when Israel as the "vine of Sodom" with her "grapes of gall" (Deut. 32:32) was crushed again for a final time, with the level of bloodshed in all the land of Israel at record levels, particularly in Jerusalem. They were called the "days of vengeance" (Isaiah 63:4 cp Luke 21:22), when Christ promised in Isaiah 63:6 that He would "tread down the people in mine anger, and make them drunk in my fury, and I will bring down their strength to the earth."
You are exactly correct that Zechariah 14:4 is predicting the time of this event when God took vengeance upon His enemies at His return, but you are placing the wrong date on it. We have archaeological evidence today of earthquake rubble fields, lying on the slopes of the Mount of Olives, that prove the fulfillment of Zechariah 14:4-5 has already happened. (Which from my studies I believe to have occurred on the day of Pentecost in AD 70.)

. Very interesting reading, and a very thorough presentation with attention to scripture related to this topic.
As for the scripture text in your post's title, the prophecy of Hosea 6:1-2 was fulfilled long ago in the time of restoration after Jerusalem had fallen to the Babylonians in 586 BC. The Lord healed the nation after the 70 years of exile, when He had torn the people from their homeland. He gathered and brought them back into their land in the post-exilic return, when He "raised them up", "healed" them, and "bound them up". It amazes me that there is a general disregard of this period of Israel's history, when God gave them a "reviving" in the land of Israel (as Ezra 9:9 claimed), under their own high priest again. Ezekiel 37's vision of the valley of dry bones come to life again is related to the very same time of reviving during the post-exilic return. To apply this Hosea 6 text to a future expectation for the Jewish people is to ignore the record of how God already accomplished His promise of this restoration of the nation during post-exilic days.
