Would widen the scope - make it a time window until next patch that upgrades gear ilvl, thats gonna be a few months at least.
And rewards should be something more meaningless, like housing items/walls in raid design, glamour lvl1 item like a boss weapon or gear piece, adventure plate design in the style of the raid, titles. If you wanna give speedrunner a reason, then gear with set bonus that only drops while the content is live.
