Scott, no. You need to move over the connectors from the 5V to the 3V and you need to change the speaker to 4ohm and the battery and harness to 2.4V. G
I have not had any problems bending the heat sinks as long as your not bending a current crease back the other direction.
I just use a vice and pliers. I recycle the 5V in many cases or modify the 3V. Sideways, upside down, rear facing, side facing, etc... G
