What if gravity isn't a force, just an illusion of expanding spacetime's momentum?

Could it be possible that gravity isn't a force per se, rather
spacetime expands at a rate proportional to the mass occupying it and
the distance from the mass (like an expanding light cone, only made
from the spacetime 'fabric'), and the 'force' of gravity is really
just an illusion that's an artifact of the expansion (like centrifugal
force isn't really an independent force)? Standing on the surface of
the earth, we are not being forced down, it's spacetime being expanded
into us (which accounts for all the quirks of gravity that make it a
far different beast than the other forces of nature).
The concept would require an 'event horizon' of sorts at which
spacetime begins folding (into a different dimension?), e.g. if the
forces of expansion are disparate (like me vs. the earth), the weaker
expansion force 'loses' and folding occurs in the expanding spacetime
of the weaker force (mine loses and is overwhelmed by the earth's); or
if the forces are similar (like two massive bodies in close proximity)
folding occurs at a rate greater than either expansion, 'pulling' the
two bodies together. Galactic expansion would be explained by the
fact that the two expansion forces (two distant galaxies) are powerful
enough to interact, but the point of interaction is distant enough
that folding does not occur, and the spacetime being created between
them is actually pushing them apart at an accelerating rate
proportionate to the accretion of new spacetime between the two.
Consequently, this theory would explain the conundrum of why gravity
and the accelerating expansion of the universe coexist (and eliminate
the need for 'faith-based' dark energy... both are explained by the
same mechanism, just operating on opposite sides of the 'event
horizon'), and the irreconcilability of general relativity with
quantum physics (i.e. it wouldn't be necessary to reconcile gravity in
quantum physics any more than it's necessary to account for
centrifugal forces in quantum physics). This explains why in our own
galaxy we observe gravity attracting bodies to each other at an
accelerating rate proportional to mass and distance (the force at
which the expanding fabrics meet each other is great enough to induce
folding), while on much larger scales (distances at which the
'momentum' of the expanding fabric is weak enough that folding doesn't
occur and instead just push against each other) something seems to be
pushing bodies apart at an accelerating rate proportionate to mass and
distance.
Are there any major, glaring laws of physics that would violated by
this theory or make it impossible?
