No, the Nikon battery chargers are very different than the Kodak ones, so there's no good way to make one work - short of redesigning the entire thing, that is!
The later Kodak 5xx, 6xx, & 7xx series all use the same charger. This consists of a simple AC-DC power supply that plugs into an separate battery charger base where all the charge control circuitry is inside the charger base.
The Nikon chargers all contain the control circuitry inside the power supply housing, so you plug into the battery pack directly.
The Kodak packs have six cells in them, an overcurrent auto-resetting circuit breaker and a thermistor (sends pack temperature to the charger control circuitry). They're pretty basic. The very early packs were NiCd, but were replaced with NiMH and those are about all we'll see at this point.
The older Kodak cameras (prior to the 5xx series) all had NiCd battery packs built inside the camera body itself. As I recall, also six cells with a circuit breaker and thermistor. Those use just an AC to DC power supply - the Elpac one mentioned already. The charge control circuitry is part of the Kodak board inside the cameras.
If one opens up the camera, the pack is easily removed. One can take that to any of these battery specialty shops - I use Batteries Plus - and they can rebuild the pack. I used to do this myself, but it's actually cheaper to take the pack into the store than it is to buy the cells retail and rebuild them myself.
Elpac was a maker of small DC power supplies for all sorts of portable electronics makers, not just Kodak. The ones Kodak used were not specific in any way to Kodak, unlike the later (5xx and newer) units. So, they're always available on eBay - all you have to do is watch for a week or so and one will turn up.
The charger power supplies and actual charger units for the later Kodaks seem to have dried up, unless one buys another camera that comes with a charger in the bundle. I see a lot of chargerless cameras out there, too. I think a lot of them were separated from their chargers and the chargers sold off first for some odd reason.
I know I'm guilty of that myself. I have three Kodak bodies: a 560, a 760 and a 720x and only one charger at this point. I had two chargers, but one went to Jarle some time back when he picked up a 720x without a charger. I also picked up my 720x sans charger. For that model, I bet they were once used in photojournalism and things got split up and sold in lots to then eventually find their way separately to eBay.
Battery packs for the later model Kodaks are readily available on eBay, so I would not fool with rebuilding them at this point. The last few I picked up off of eBay within the last year were priced some 25% less than the cost of rebuilding.
Note, too, that there are *two* power supplies out there for the newer Kodak units. One is used with the battery charger, and the other is used to power the camera without needing a battery pack (i.e. studiio use). The camera power supply and the charger power supply are not interchangeable. I see the camera power supplies on eBay all the time, so if anyone needs one of those they are out there.
