Of course one can learn a lot from Feynman's diagram approach starting with a spin 2 symmetric small tensor field on a non-dynamical global Minkowski background. Like the BCS superconductor Feynman has to sum an infinite series of a restricted class of diagrams to get a QFT non-perturbative version of Einstein's 1916 classical field equations

Guv(curved space-time) + (G-string tension)^-1Tuv(all non-gravity fields) = 0

where now we know from Type 1a supernovae data et-al that the hologram idea of 't Hooft & Susskind seems to work! i.e.,

dark energy density in our past light cone ~ (area of our subjective future event horizon in our future light cone)^-1

in Igor Novikov's globally self-consistent loop in time needing the Wheeler-Feynman principle with our future horizon as the total absorber giving net retarded causation from the John Cramer transactions (see also Mike Ibison's papers).

Instead the spin 1 gravity tetrad fields are emergent macro-quantum coherent order parameters from the post-inflation vacuum superconductor possibly deeply connected to the 8 gluon Goldstone phases conjugate to the 8 color charges of SU3 QCD. The tetrads are EPR entangled states of pairs of Penrose-Rindler qubits in the pre-geometry (J.A. Wheeler)
Einstein's spin 2 gravity field used by Feynman in his QFT approach are composites of pairs of tetrads, but in QM

1 + 1 = 2 + 1 + 0

also like entangled Cooper pairs in a BCS superconductor there are states beyond the S-wave relative orbital state.
