Set Apart: Some Dice Tricks that need help

So, I'm looking at my Tarot-fantasy-Exalted hack, and it's from way back when when there were red and white dice, and because of that there are some moves that depend on dice color to work. Can you guys help figure a way to convert them?

Fortune Smiles: When your red die rolls 6, on your next roll, don’t roll white. Get a white 6 instead.

I like how this creates streaks of luck.

Champion’s Wager: Instead of rolling+cool, you can roll a red die; the MC rolls the white die. If your die shows a higher number than his, you get a 10+. Otherwise, you miss.

This one, I'm not sure about at all, since it bypasses the whole dice system, but the all-or-nothing effect is pretty neat to me.

Fortune's Favor: If your roll, before modifiers, is a 10+, take +2 forward.

Maybe? "10+ before modifiers" is still exactly a 1 in 6 chance of triggering.

Champion's Wager: You may invoke this move instead of rolling +cool. Roll 2d6+1 instead, and reroll any 7-9 results, until you get a 10+ or a miss.

(The +1 is so it's as close at it can be to 50-50 odds, but still slightly biased in favor of the MC)
