We're going too off-topic with this.
But a stealthy bomb truck can be very good strike payload... safer too as it will not have to sacrifice low observability. I think it was asked for by IAF only, as ADA did away with the side bays & enlarged the inner one, then splite it into 2, as in present iteration.

AMCA Mark1's (Mark2 will have 110kN engines) loaded weight from runway is 25t+... so 12+4+2 will be no sweat.
17.5t is for MWF, you might have confused the numbers.
