No! You would be building a "S" trap which is outlawed. A better solution would be to install a AAV, (air admittance vent) just off the trap. (see image) Good luck, Tom

Each side of the sink has its own trap? Does the drain come out of the wall or go down into the floor from the traps? Back to you. Tom

One trap for both sinks then goes into the floor

Sorry! You said traps so I assumed a trap for each tub. You do have the room to install a AAV but you will have to replace the elbo going into the floor with a sanitary tee on its back followed by a street ell and 2 45's in the vertical line to connect back, The AAV goes in the tee. Good luck, Tom
