Hg(SO4) + 2 HCl → HgCl2 + H2S04? Would that work? or would it rather make odd mixture of water and sulfur-oxygen compounds?

How would you separate the two products?

i forgot to mention it was in an aqueous solution and HgCl2 would precipitate.

No, HgCl2 does not precipitate. It is fairly soluble, appr. 7 grams per 100 ml. Hg2Cl2 (the mercury(I) salt) is insoluble, but HgCl2 is soluble in
water.
If you really want to make HgCl2 from HgSO4, then you have a fairly hard time doing that. HgSO4 is only very sparingly soluble and it hydrolyses in
water. It becomes yellow, as soon as it comes in contact with water, due to formation of insoluble basic sulfates.
You will have to dissolve the HgSO4 in dilute sulphuric acid and then you have to add a lot of hydroxide. This will precipitate yellow HgO, but
unfortunately this will be heavily contaminated with sulfate, due to the insolubility of basic mercury sulfate. HgO then in turn can be dissolved in
dilute HCl. Using this route, do not expect very pure HgCl2, but it may be good enough for your purpose.

Hypothetically HgSO4 would work as a miracle catalyst that would cure the world from all kinds of disease

thank you for the input
