I've tried flea 2AE monoblocks with VSM-MXs and the sound was pale & underwhelming. Merlins present a stable high impedance that would appear to be SET-friendly, but they aren't sensitive enough for low-powered SETs. By comparison, I am able to get slightly more sensitive Watt Puppies to work well with 2A3s using autoformer impedance multipliers. This is surprising, knowing the uneven impedance curve and difficult phase angle of the Wilsons. However autoformers only degraded the sound of the Merlins with flea SETs.
You could probably make it at 20wpc.
