Gearing could be your savior. What is the transmission in this bus? Final drive? Tire diameter? If you had 3+ gears designed to max out at 10k RPM at 50mph, even a puny Nissan Leaf motor putting out 280Nm might still be sufficient to get the thing moving. I feel like the "comparison" here is to calculate torque to the axles of the stock drivetrain (including transmission and diff), and see what that looks like if it were geared very tall for a lower top speed.
I dunno what factory BEVs are going for in your neighborhood, but buying one or two Leaf wrecks and salvaging the components is probably the cheapest way in. At 60mi range in a big ol' bus, the optimistic parts cost I would keep in mind is £10-15k just about any way you slice it.
