Yes, you have taken on a difficult project here. You will be lucky if there is enough room to fit a decoder on the top of the motor.
If you are worried about the decoder shorting on the inside of locomotive- use some .005 thick plastic and put in the inside of the shell were the decoder will fit.
If you are thinking about putting the speaker into the cab you will need to add glazing to the windows. That way the cab will be come an enclosure. If you don’t , you will not get very much volume.
You might want to think about using a TSU-GN series decoder. I say this because it looks like it will be a tight fit to install a capacitor. On the GN boards the cap is on the board, but they do add to the thickness of the board .
You might think about using a smaller speaker and mounting in under the drive lines and letting the sound out the bottom of the unit.
I will be waiting to see your progress. Photos of course!!
