I find it highly unlikely those are truly variable speed inverter units, as the packaging shown does not make the same inverter claim as the web offer. However, I am certain they actually could make you a inverter type window unit, especially if they already make split type inverter units. But for just one or two units, cost would be very high. You would have to be very specific what went into those units, the quietness, the efficiency, input voltage, dimensions and weight all must be agreed upon, and shipping costs calculated.
