Joel, not exactly. I don’t know what kind of masts you guys have, but probably not in the 100 ft range.
The halyard stretches only on the length of the mast plus the line from the mast to the clutch (if you run it to the cockpit). Most of the boats we talk about here have masts in the 40-45 ft range (P dimension). Add 10 ft for mast to clutch distance. So we are talking 50-60 ft max. Additionally, the problem is not with the stretch itself. Once you hoist the sail and tighten the halyard, you induced most of that stretch already (it is a good 1+ ft!). The issue is with how that stretch varies with time and load (creep). In most applications, that creep is substantially less (single inches vs. 1-2 ft). One of the funniest parts is that Dyneema has substantial creep under a static load (more than many other less exotic lines).

Halyard tension should be adjusted during a race - less downwind, more upwind. You would need to check the sheaves to see if they were changed. Rope compatible sheaves are more V shaped. Rope is more of a DIY project unless you have the tools. You still the need the rope tail. Dyneema is lighter than wire, but I doubt you would notice the difference on a 12,000 boat.
