Goballoon Racing - some thoughts on card play possibilities

After posting about this new, updated idea using that simple race mechanism I'd mentioned before, I had a few different ideas about how to do card play. here are some of them, stream of consciousness style:

1. Maybe just make a few (3-4) different effects, and give everyone a deck of 15-20 cards, each card with one of the effects paired with one of the racers/balloons. You'd draw a small hand, and then your options would be to jump on those particular airships, and get those particular effects. So if you want majority on a particular ship (and you had a card fort hat in hand), then you wouldn't get much control over the effect. On the other hand, if you want a particular effect from one of your cards, then you might not get influence on the ship you want...

2. Maybe instead of a hand of cards and individual decks, just have 1 deck, and deal out a display of cards. On your turn, play one of the cards from the display (then refill it). This removes simultaneous play -- is that a good thing or a bad thing?

3. Maybe separate the racer from the effect on the cards, and just deal cards with effects into 5 slots - one slot per racer (like in Keeping Up With The Joneses). On your turn, you'd choose a card to resolve the effect, and you'd get a gobbo on the ship who's slot that card is in. And in this case, probably don't refill the display until the end of the round, so you can't all pick the same balloon to jump on.

4. Is this an interesting twist? Leave the card effects in play, and the next time that ship gets jumped on, the new effect <i>and all old effects</i> will resolve (a la Wingspan or Deus).

I could see any of these formats working, no way to know what would be best, so I'm soliciting opinions in the comments: Which of these ideas sounds best to you, or can you suggest a different format you think would work better?

The goal, I think, is to have a quick playing, fun game... not too time consuming, not too thinky, not too AP provoking. Is simultaneous play better fort hat purpose? Or is it better to take turns? Let me know what you think!
