Though I'm not quite sure how I feel about those particular items, I absolutely agree that the summoner class should have more weapons and items outside of its standard familiar based attacks. As of this moment, calling the summoner a "class", is a bit of an overstatement, especially considering it pretty much just piggybacks off of magic labeled gear. Three things I would really like to see at some point and time within Terraria development;
1: A helmet to go with every mainstream progressive armor (Summoner based armors for Hollow, Clorophyte, ETC).
2: A large step away from the magic class's core structure as well as high DPS compensation for the summoners stupidly low defence.
3: A long line up of unique, summoner like attack items that greatly step the boundaries of just familiar staffs and sentries.
If made properly, I could easily see the summoner class coming to be one of the most entertaining classes in terms of playability, however I feel as if a big increase in unique summoner standalone weapons are required before this could become a possibility. I'd imagine most of these weapons would be very similar to magic style items but with a bit of a summoner aspect to them. For example, imagine a weapon that summons some form of animal/creature spirit to charge forward with great knockback, or perhaps even a giant translucent claw that swipes in front of the player. Gravity balls that prevents trash enemies from moving, ropes/platforms/crafting tables that can be temporarily summoned where ever clicked, a summonable healing station that quickly regenerates life when near by, a group of light beams that shoot from the sky and cover a large area around the player, the ability to brainwash a trash enemy and have them fight for you, a weapon that shoots out WoF's digger enemies to move through the ground and fight for you. Creativity is truly the limit here, and might I add that the summonable sand tornado implemented in the newest update is a great step in the right direction.
I doubt it would be unreasonable to even convert some items really. The Bolder Staff, Nimbus Rod, Rod of Discord, and Bat Specter for example would make for some pretty rad summoner items in my opinion. This however is all theoretical, though I do have confidence that there may be A LOT of summoner class tweaks within the upcoming update since Re-Logic has stated they've dedicated 1.3.6 to filling in the gaps they missed, I greatly doubt it will be anywhere close to the scale at which we are hoping.
Edit:
I greatly respect this idea. I would have absolutely no problem with this being added to the game.
