Pillars as placeholder goal keeper in adult size games?

Currently we foresee a 1-on-1 game on an empty goal in adult size. Maybe games would look more interesting if we had one of the obstacles / pillars as a kind of a (stationary) ‘goal keeper’. I propose this as a minor update to the rules for 2017. Are there any opinions on this idea?

I actually think it would make AdultSize games more difficult than the other leagues if that pillar is treated as a goal keeper as well (meaning special protection and no touching allowed). In Kid and Teen Size inactive goalies are taken out after some time. The pillars would remain there and could potentially lead to a many fouls…

I would leave it out for this year and introduce it as a future development for next year.
