Abstract
We prove that given two compact oriented -manifolds and with satisfying only a mild hypothesis, there is a hyperbolic -manifold arbitrarily ``closely related'' to and such that does not embed in For instance, as a weak version of our main theorem, if is a rational homology sphere then for any the -manifold can be chosen to be -equivalent to Our techniques rely on the construction of -manifolds with complicated Frohman--Kania-Bartoszy\'nska ideals, using the strong approximation for -Witten-Reshetikhin-Turaev quantum representations of mapping class groups of surfaces.
