You should post more info of what you are looking for. Chainring size combo, chainline desired, and Q-factor (thread width) if important.
What type of frame is this going on? Swapping between Road & MTB cranks could cause clearance issues in the area of the chainstay.
About using 8 speed chain on a 11 speed crankset. It may work, but the shift aids (pickup pins) may not work quite as well.
