Some people have said they wish GOTG had metal ramps. We know this has almost an identical layout to MET. I'm wondering if MET's ramps could be used...?
If the ramp entrance locations and widths are identical, all someone would need to do is 3D Print a small plate with a raised 'M' logo (plate adheres to ramp from underneath) and then recreate the Premium ramp decals to smooth over that area for aesthetics.
From there, as long as there were enough mounting locations to support the ramps, the GOTG ramp-mounted flashers would need a mod to either support or relocate them. Thankfully you now have 4 giant holes on the back-panel to which you can start mounting flashers or toys that can hold flashers. Just a thought.
