No, the circuit as illustrated will not work.
All that the lower pot can do is determine whether the signal is either passed via the capacitor to the second tone pot or diverted to the third lug (a dead end). It is, effectively, acting as a switch.
The upper tone pot will have no effect other than loading of the pickup(s). With no connection between the pot lugs and ground, the combination of resistance and a capacitor cannot act as a low pass filter.
