Which does have some appeal, I admit.
Still, we *know* that quantum gravity effects will be relevant at some point, so this type of splicing together may not be as straightforward as it appears in just GR.
Do you think something like the graviton could be the answer? Is there potential to discover a graviton at the LHC like we did with the Higgs boson?
