Considering the highest he could reasonably expect to finish is P7, I don't see any problem with his grid position. He'll get half of them back at the start, and will have lots of new rubber for the race.
Unfortunately I don't share your optimism. As mentioned above, its a very short sprint to the start and starting from the dirty side it will be tough to make up places.
Regards the rubber the super softs are expected to melt like action man under a magnifying glass tomorrow, so having extra sets of those is no help - the majority of the race is expected to be run on softs and everyone has equal numbers of them. Except Red Bull, who were weirdly slow on their super softs in Q1.
He should be ok for some points, but I'm fearful of the first corner. It gets really tight around there, could go well, could go very badly.
