Odysseus: Winds of Fate - another idea

I just came up with an alternate 'investment' idea for Winds of Fate. Recall that the basic structure is that players bet or invest on whether Odysseus will make it home or not, and then attempt to influence each Adventure along the way to that end.

The new idea is that there is a track indicating the 'value' of each coin invested. Players earn coins through "good play" in the Adventure mini-games, and then they can either invest them (a bet that Odysseus will return home safely), or not.

Each adventure won by Odysseus will increase the value of the track, thereby increasing the value of coins invested. Each adventure lost will decrease it. A safe return home will increase the value by several units. At the end of the game, the track will indicate how many points each invested coin is worth. Uninvested coins are worth 10 VP apiece (the track would start at 10).

So betting on a safe return could end up in lost money if Odysseus loses too many adventures along the way, but could end up with a positive return if he doesn't. Betting on failure means not investing coins. Of course coins could also be spent in order to draw cards, or otherwise influence the individual adventures.

Any thoughts on this alternate structure?
