Looks cool!

Had a similar idea for adding guns or bullets for the bullet targets. Also adding a cop car to my playfield soon. I have a good idea for the freeway entrance ramp and need to fabricate it....should look nice and like it belongs.

I made my own dynamite bombs too and placed them on the two drop target banks. Looks much better with them on the machine and it matches the fact you have to diffuse the bombs, so might as well have bombs there.

Also wanted to light up the speakers like you did. Haha. Just need to fix GI issues before tackling any more mods.

Also installed a dual light topper.
