Answer

"Depending on the timing" means it depends on the time the event takes place. This usually implies you are very busy and it would depend on the time of the event for whether you can attend or not. The sentence you created is correct

Answer

Hi, 
what do you mean "very long"? Are you referring to the duration of the lunch, or to the fact that the date shouldn't be too far into the future?
Thanks
