John Deere 9300 backhoe attachment stationary inside

So I was just kicking around an idea of a stationary backhoe inside a building. Now here is what I am questioning if I were to purchase a decent size backhoe attachment like a backhoe attachment for a bulldozer and mount it stationary in the building, could I pull my kubota svl 90 up to the outside of the building and run hydraulic lines to the backhoe (inside) from the aux lines on the ctl and be able to use the backhoe attachment? Would the hydraulics/pump work that way? Reason I ask is debating about on a small scale doing some soil processing inside during the winter. This idea would eliminate running exhaust inside a building but not sure if it would even work. Am I too off the wall with my idea? Also the soil processer only has an electric motor. Just was looking for input if it would work or not?
