Actually it might end with nothing. Most of pikes caught in lakes by me were with empty stomachs. It doesn't mean that they had nothing to eat. Not at all. Simply they weren't eating for some time and after that they saw my lure...
That's about catching them with lures. If you plan to use some fish traps then results might be better.

Anyway, if you got a possibility to get another 2 pikes instead of these removed then have a try!
