 act: In an attempt to probe the extent to which excitations of the QCD vac
 uum deform spacetime\, I add weak-field Euclidean GR to the process used t
 o generate ensembles of lattice QCD gauge fields. This is done in a manner
  that evades no-go theorems that plague the coupling of classical and quan
 tum theories. To implement the Euclidean path integral for GR\, the positi
 ve action conjecture (Gibbons\, Hawking\, and Perry 1978) is implemented o
 n the lattice. Preliminary results\, limitations\, not-yet studied systema
 tics\, and some possible phenomenological applications of the approach wil
 l be discussed.
