would a simple reaction between elemental mercury and household vinegar produce a solution of mercuric acetate?

No, because Hg is well below H on the electrochemical series, for the formation of both Hg++ and Hg2++, and besides acetic acid is not an oxidizing acid which means that in this instance the acetate cannot form via the oxide.

I would suggest forming mercuric chloride by directly chlorinating the mercury with Cl2, then reatment of that with conc. acetic acid, that might do the trick.

On the other hand, I would suggest the direct chlorination of mercury by Cl2, but instead of treatment with conc. ethanoic acid I think a double displacement rxn would do the trick. Such as
Pb(CH3COO)2 + HgCl2 --> PbCl2 + Hg(CH3COO)2

PbCl2 is quite insoluble and can be removed by filtration. Otherwise, HgSO4 could be used since PbSO4 has a lower solubility than PbCl2.
