No, it won't work at all.
The lens that's on the camera is what you think of as a camera lens: it
forms a real image on the sensor. The "lenses" that mount into the
adaptor sleeve are not normal lenses at all, they are afocal converters.
They don't produce a real image at all, instead behaving more like a
telescope or binoculars in providing angular magnification. These can
be mounted in front of a regular camera lens to change the field of
view, but are useless on their own.
On the other hand, the Tamron lens you're talking about is a real
image-forming lens. To use it, you'd have to remove the existing lens
from the camera, but the Kodak camera isn't designed to do that.
There's no way to mount the Tamron in front of the existing lens and
still have the assembly focus to infinity. (It is possible to mount a
35 mm camera lens reversed in front of the permanent camera lens for
extreme closeup work, but that isn't what you seem to want).
If you were really determined, you *could* get someone to machine a
custom mount that held a telescope eyepiece at the focal plane of the
Tamron lens, thus building your own afocal converter, and then mounting
the camera onto the whole assembly so it looks into the eyepiece. But
you'd be better off starting with a telescope, not a camera lens.
