Is this legal?
Will it help with the input spikes?

Is it legal? No. Custom circuits are not allowed to modify power paths.
Check to see if the RoboRio is plugged in to the correct spot (This is a boost-buck port so it is less affected by power spikes).
Next, look at the driver station dashboard. There should be a graph of the battery voltage. This should give you a hint as to where the issue is.
I suspect that your battery is low and you are using a high traction drive train with an incorrect gear ratio.
