I would say no. That is alot of weight even for 2x10 beams. It also depends on the joist sizes and O/C as well. I am also not an engineer, but will be very soon. (as long as I pass, haha). Its worth getting it checked by a P.Eng. My guess is he will say no as well.
The good part is that the wood goes through an elastic period. It is a ductile material, meaning it will most likely deform before failure, which you can visually monitor.
Best advice is to contact a licensed structural engineer and show him the floor plans.
Good luck.
