I would be more concerned about why the floor is spongy, than putting down a quick fix. Until I satisfied myself that the cause has be arrested, I would not add more wood to the problem.
Assuming that there is no water damage involved, I would look at going straight to one of them new hollow core vinyl floors. You would gain some R-value and probably enough structural strength to solve the problem of the spongey floor. Forget about mechanical fasteners, with all the high tech adhesives on the market. When I layed an engineered oak floor in our old Airstream, I layed the starting course with PL Premium at the curb side. Layed the remaining floor W/O adhesive, to the curbside course. When I sold the Airstream, the floor was as flat as it was the day it was new, but as many of you know I'm a fanatic about humidity control in my camper. After a couple of years of poor humidity control, the floor looked like the rolling waves of the Pacific.
That's where the new vinyl planks win out, unless you get them hot enough, nothimg will make them curl.
