LotR TCG: Full Trilogy Format (Game 1): Rangers/Moria vs. Fellowship Archers/Uruk-Hai

I'm trying out a format which is meant to place all of the original three blocks together to tell one complete story. The fellowship must survive all 3 adventure paths in order to destroy the ring! Here are the rules I'm working with, in development:

1.) Both players bring 3 separate, complete decks. One First Block, one Second Block, and one Third.

2.) Play begins with the Fellowship block decks, with all standard rules in place.

3.) If a Shadow side gets a win at any point in any game, the game is concluded. Winner is that shadow player.

4.) If a Fellowship side makes it to site 9 and survives in the Fellowship or Towers block game, that game is immediately concluded, and both players move to the next block, with the following rules:

a.) The winner from the previous block plays their Site 1 for the next block, and goes first.
b.) Both players create a new starting Fellowship, with a total twilight cost of 4. Characters can be selected from the new deck, or kept from a player’s fellowship as it stood at the end of the prior game.
c.) If any characters are kept from the prior game as part of the next game’s starting fellowship, the owning player may keep any number of fellowship cards in play which were on that character at the end of the prior game. That player must pay the total twilight cost of those cards which were kept at the beginning of their first turn.
d.) Players may select a new version of Frodo and a new version of the ring from their new deck.
e.) All wounds are removed from companions.
f.) Frodo starts the next game with the same number of burdens as were on him at the end of the prior game.

5.) Dead piles apply only to single games for the sake of spotting characters in the dead pile. However, if a unique character is ever placed in a dead pile, no copies of that character may be played in any future game.

The two decks featured in this game are:
1.) Super-Boromir, Aragorn and the hobbits paired with the archers of Moria.
2.) Elven/Dwarven archery, with the fighting Uruk-Hai.
