longisland,
Danica aint gonna happen. She's already ruled out F1. She's also getting a bit old for a debutant, even though women don't decline as fast as men.
Here's my dream grid:
Red Bull: Vettel/Hulk
That's not going to happen of course, but it would be good for Hulk. The problem is, that like Mark, he is considerably heavier and taller than Vettel, so he would suffer the same inherent disadvantage in car setup due to the lower amount of distributable ballast weight.
Merc: Hamilton/Rosberg
I think this combo should be kept. Both are very quick and we didn't have the sort of mud-slinging we saw with VET/WEB or ALO/HAM in 2007.
Ferrari: Alonso/Räikkönen
That one actually does happen, although I think Ferrari are window licking mad. They obviously lerned nothing from the Villeneuve/Pironi or the Mansell/Prost pairings. Two alpha dogs in the team has almost never worked since the 70s.
Lotus: Massa/Valsecchi
I'd really like to see Massa being given a late chance as the team leader. Also his experience would help the inexperienced Valsecchi. RoGro is out. He's done some decent races this year, but considering his obvious talent, I think it is a little to few and too late.
McLaren: Button/Vandoorne
Same combination as with Lotus. An experienced winner paired with a promising, but inexperienced upstart. For Perez it's the door. May it not hit him in the arse on the way out.
Force India: Sutil/Sam Byrd
I think, except for his brilliant drive in Canada, di Resta hasn't done much to set the world ablaze, so Merc could park their test driver in a Force India. Sutil has been with the team since they were still called Spyker. He deserves some loyalty and he usually puts in strong drives if the car isn't falling apart at the seams.
Sauber: Rubens Barrichello/Cyndie Allemann
Seeing Rubinho back on the grid would be great. Somehow it felt weird when Schumacher left and there was nobody left, who had actually driven in the same race with Senna. This could bring the warm fuzzies back for a year or two. I'm weird, I know ;)
As for Cyndie. Well, I think she's one of the women, who could have made it in openwheelers, if ever given top material. She used to beat the crap out of Buemi in their karting days. Everyone, who can drive an Indycar for a second-tier team to 4th in torrential rain is F1 material in my book. On top of that she's cute and her thick french accent is hillarious. (I'm shallow, sue me)
Williams: Glock/Wolff
With their recent string of crap seasons, Williams need a driver who has experience with wonky cars, not someone who perpetually wrecks them. That means - exit stage right: Pastor Maldonado. Except for the 3rd place at Canada qualifying, Bottas hasn't done much, so I think he should be Caterham-bound. Suzie has shown in the young drivers test that she isn't as slow as people think, so she should get a chance and the PR could create more funds.
Toro Rosso: Vergne/Sainz jr.
Nothing much to say. Just sounds right.
Caterham: Kovalainen/Bottas
An all finish lineup could help attracting funds from Finnland and both deserve to be in F1.
Marussia: Petrov/Sirotkin
I'm with longisland on this one. Russian team, Russian drivers, Russian coins.
