[simpits-tech] Electronics question

I am wondering if this will work.
I have a voltage divider of two resistors, set to put 2.5V at the output X when 5V is set over it.
I want to use a logic chip (74HC74 dual Dtype flipflop) to pull the output to 0V or 5V, depending on how a rotary encoder turns.
I have found how to turn the signal of the rotry into a high on either of two outputs of the flipflop.
Now I want to use two transistors to short out either of the resistors so that the output X is connected to either side of the divider.

A and B will go straight to the chip with only a diode in between.
Will this work?
Can I use any regular transistor?
Regards,
Jeroen.
