Wire sheaves are generally v-shaped in groove profile. V-shaped grooves will damage rope, and cause them to wear very rapidly. Rope sheaves are u-shaped in profile. Also, the wire sheaves may be too narrow, since generally, line of the same strength will be of larger diameter.
Generally, you'll be better off with high-tech, Spectra-core or Dyneema-core lines rather than wire for your halyards. The new high-tech lines have about the same stretch as the wire, but are far kinder on the hands and far lighter.
The winches, if they are reel-winches, which are wire-only.... will need to be switched out. Reel-winches are damn dangerous, and if you're not careful with them, they can hurt you pretty badly.
As for the mast top setup. The two lines led aft are the main halyard and the topping lift. Two of the lines forward are the jib halyard and the spinnaker halyard.
The last one may be a topping lift for a spinnaker pole, but that is more likely the smaller block that is mounted facing fowards on the mast. If you had a spinnaker pole track mounted on the mast, the forward block one might be for a pole end uphaul/downhaul, and the mast-top would then be used as a pole topping lift.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
