With reforging for specific results, there is currently not enough data, at least not that I know of, to shoot for more than one over-capped property. And even if there was, the odds of getting what you want and the price of higher level runic charges would send your costs through the roof.
Because SSI, HCI, DCI, DI are all stats that are capped through a combination of your entire build, it would be hard to advise on what to do about these without knowing what you've got, and what you want from it.
But as Hit Spell is what you are interested in, I can show you how to get max possible Hit Spell clean, which would be 70%, and then you can imbue whatever else you need.
Use a copper runic with no options to increase the power of the reforge. The only thing you want to do is set the options that give you "Vicious / of Slaughter", and nothing else.
It will take you several shots until you get a 70% Hit Spell clean in the spell you want, I think the odds are something like 1 in 25. At about 30k a shot, it could run you close to a million for this weapon, and then again you could hit it on try #1.
After that PoF and imbue the rest.
