Default is it possible? (speed of light)

Is it possible that speed of light is infinite in a flat universe, but
finite in a curved one. Imagine, in the expanding balloon analogy,
light does not follow the curvature of the surface of the ballon
(spatial dimensions), but travels on a straight tangential line in
space&time, so the propagation delay we observe is just due to the
curvature. If this is true, speed of light would be measured slower as
the distance increases, and light emitted from a quarter distance of
the universe could never be observed. Any comments appreciated.

The speed of light in tunneling experiments is much higher than c ( a theory
says infinte plus delays ).

See Nimtz experiment

No, it is NOT possible.

You dismiss this idea too easily. What observation or experiment proves
it impossible? This gives an explanation as to why speed of light has
this certain value as we measure it locally (linked to the amount to
curvature). A measurement performed on earth would not be able to show
a meaningful difference in the speed of light within experimental
error, a measurement must be done on a very large scale. Does anyone
know if this idea has been explored?
