Floor structure is in question

Well, I am in a dilemma. Bought an old House, 1905, gutted the 2nd floor bathroom and would like to put a cast Iron tub in. The tub with water will weight about 500lbs. When ripping out the bathroom, the subfloor , which was diagonally placed 2 x 6s that went from one room to the other, have been taken out. The floor joists have large holes from old plumbing plus holes for new plumbing. I am worried that the diagonal subfloor boards did more then act as just sub flooring, but distributed weight to a larger surface making less load in the bathroom...

Can I sister the joists and call it a day or should I think about something more invasive.

This problem has been keeping us from moving forward.

Thank you in advance.
