If you built a large roofed area so they were happy to go out all day on yucky days, it might be doable (put the roosts right down near floor level to avoid getting-up-there problems with two parallel roosts).
BUT, I would not really suggest that as an ideal situation, and it will cost you a significant chunk of change to build a roofed area *anyhow* (properly, so it stays put over the years). It would probably be better to bite the bullet and just build a whole new thing, preferably *including* a roofed outdoor area but also giving them more indoor space.
HOwever if you are renting (sounds like maybe you are?) I think your better solution would be as follows: only get 5 chickens, and make a small knee-height roofed area they can use on rainy days (this is much simpler and cheaper to do). Honestly I do not think it would likely be in your best economic interests to get 10 chickens, as remember that doubles the amount of chicken feed you must buy... year round, regardless of how well they are laying. Unless you live in an area where backyard eggs can be sold for a whole big lot more than the cost of production. But most places that's not the case.
JMHO, good luck have fun,
