If both interfaces are talking to the same Access point on the same 
frequency, it's going to be worse as WiFi can only talk to one thing at 
a time, and the two interfaces will compete for bandwidth.

If you set up the access point with a different SSID for each frequency, 
and connect an interface to each, you might get a small amount of 
additional bandwidth, but not a much as if you had two 5GHz access 
points on different frequencies and SSDs.
