Will main stage run on Mac book air

I am considering going to a software driven live performance music keyboard set up using Main Stage as my sound source. Will a Mac Book Air be powerful enough to run the software and external devices? Outboard stuff would include a digital I/O device and a 49 and 61 key controller both capable of midi over USB. I plan on using some plug ins as well: Arturia v-Mini, IK SampleTank, Alchemy, Arturia Analog Lab suite, to name a few. If the MBA can do this, what memory and hard drive configurations would be required?
