One thought would to be search for a spell similar to the Feat. I think there is a spell which augments your next summon spell. I can't find it in the SRD, but I believe there is one in one of the FR products.
That is worth exploring. I have access to all the complete books and I own a few other d20 books. There might be a spell like that in one of them that is comparable.

The 10k per feat doesn't seem that bad, at low levels, but once you get to higher levels this can quickly become a problem. Players with lots of money can quickly create things that bypass the normal rules. I would also somehow compute the cost by factoring in the levelin which you could acquire the feat as well. Even then, it can get out of hand. For example a staff which grants Power Attack would only cost, what 20k?
I agree that it could be a problem. The characters in this particular campaign aren't exactly swimming in gold at this point, so it might not be as big an issue here, but I could certainly see how it could become a problem, especially in other campaigns.
Maybe there could be a rule to restrict how feats would apply to items - for example, a character could only benefit from a limited number of them, or only specific body locations could have them along with the limits of how many can be on that item. Of course, now we're treading even deeper into the houserule zone which wasn't my goal here.

As for the metamagic rods, yes they are very flexible in that they can be used to make any spell more powerful. But you could use them as the base, maybe cutting the cost in half (max) and applying the same rules, lessor for 1-3 Summon spells, etc.
This is more along the lines of what I was originally considering. In fact, the half-cost was my first idea considering this only applies to specific spells. However, I'm not sure I like following the lesser/normal/greater spell mechanic for this. However, their might be another way to handle it...
Given that the staff will have 50 charges, 1 charge could Augment Summoning on a 1st-3rd level spell, 2 charges augment a 4th-6th level spell and 3 charges augment a 7th-9th level spell. In this case, I'm thinking this single ability could cost 4500 gp, which is half the price for a fully charged Lesser Empower Metamagic Rod.
Too low priced? Too high priced? Let me know what you think.
