'String theory' is based on 'strings' and those are supposed to be

So, matter needs to be 'relativistic' and made from absolutely nothing.

Well, the quantum foam idea allows that, but the existence of such

I had an idea for this to become possible. I just take spacetime of GR

elements'.

These 'elements' are connceted multiplicative 'sideways', like a certain
equation for quaternions, which is used for rotations.

One unusual assumption is: points may have features and more than three

 Sure: a point is actually meant as coordinate in space, hence not really real in a coordinate free space.
 But real things are usually meant to consist of something.
 If spacetime is real and a smooth continuum, than spacetime would consists of 'pointlike elements'.

If you take  any of mathematically defined
spaces - it's built of 2 elements: a set
of something and some relation defined
about that set of something.
Applies also to "physical" space and to
spacetime.
