The jumbolino certainly has things in its favour, much shorter landing distance, steeper approach possible, better fit with its size for the probable loads. The only question mark would be range. Tankering / diversion fuel would be my first concern. But I guess if they find a steep approach or other solution, they can always find a workaround if it is indeed an issue. They also should be reasonably cheap to acquire if not to operate. On the other hand if it is perhaps a proof of concept then some other aircraft like a A318 or C300 could be sourced if the trial goes well.
