Pick and Collect linked to Map Locations

I have a requirement for a Hikashop "pick and collect" service where we would like the customer to select the store that they would like to pickup the product from after purchasing it. Would it be possible to display the map of locations in the checkout page and select the "shipping" by clicking on the store in the map? We are prepared to pay for the development of this feature if it is possible to achieve in a customer friendly way.

There would be a traditional shipping option and a "Pick and Collect" option. When the Pick and Collect option is chosen the map could appear, centered on the customers address showing the various store locations (within a set distance). The customer would then select the store they wish to pickup from which would relate to a Hikashop "shipping method" for that store.
