I'm currently using "mapLayersByName" successfully to set one active layer at a time as follows...

vl = QgsMapLayerRegistry.instance().mapLayersByName('My_Layer')[0]
iface.setActiveLayer(vl)

Can an instance of multiple layers be set using the "mapLayersByName" method?

I have tried...

vl = QgsMapLayerRegistry.instance().mapLayersByName('My_First_Layer', 'My_Second_Layer')[0]
iface.setActiveLayer(vl)

As you can see my end goal in this case would be to set the layers within that instance of MULTIPLE layers (vl) as the active layers using the "iface.setActiveLayer()" method. I notice this method is not plural (i.e. not "setActiveLayers()"). Significant?

No you can't. mapLayersByName returns a list of layers matching a single name (you can have many layers with the same name)

setActiveLayer takes a single active layer because there is only one active layer at a time in QGIS.
