I'm not sure if I understand you correctly, but I think what you're contemplating has been done like below:

I myself have Amsteel halyards with what I'll call a 'working' side and a 'standing' side. These are made together with two long thin eyes. Crew pulls the halyard's standing end down to the eye, and then there's a downhaul/cunningham at the mast with a hook that's put through the 'working' end eye of the halyard. Tension is then achieved at the mast via the downhaul.
