I don't think that's a reasonable approach.
The application process serves many purposes. First of all, it establishes the applicant's interest in joining. Second, it provides a permanent consolidation of all the information you need about the player (guild and raiding history, attitude, etc) for every member of the guild to see and discuss. Third, it acts as a rapid and efficient screening. The best player ever is not necessarily a player you want in your group, as they can very easily be the wrong players for the guild. And this works two ways as well, as the applicant can then interact with the guild to judge THEM and deem if they fit.
