Is it possible to use the verb particle 过 for future events? I know it's possible to the use perfective aspect particle 了 for future events, eg:


  你家少爷长大了准能当个二流子。


I have yet to find example of similar occurrences with 过. Is it even possible to use it in other situations than past events?
In short, yes, only for events in the near future.


  等我喫過(了)，咱們再走。 (= 喫了再走)
  等我玩過(了)，咱們再走。 (= 玩了再走) It's better to use "玩夠了" in this case.
  等我弄過(了)，咱們再走。 (= 弄了再走)


You must say "等 sb" to make it natural.

Note: this is less used than only a "了".
