See, again, you're basically saying "i don't care about 75 gear unless it can be reforged to 119" - The entire point of the OP suggestion is to *give people a reason to* It isn't direct path from lvl75 item to lvl 119 item; It's respectably gear jobs for 75 cap content > defeat content (repeat) > variety of droolworthy 119 items. It seems to me the best way for SE to profit from the undeniable 75 era nostalgia that is widespread amongst current and former players alike.
I also just want to rain death in 75 cap ballista with a 75 sam/nin ridill kclub yoichi / spirits within, namas arrow, utsusemi: ni; The sky set (except for feet or hands or something) all have like +50 hp and can get some sick synergy augments like haste and dual wield - dual wield for that kclub sounds nice.
I mean these are brainstorm/spitball ideas on a theme with specific parameters: Make lvl 75 endgame gear necessary again in order to get new 119 endgame gear that people are going to at the least, really want, and more likely will have some people saying it's required. Put a ring that grants COR a third roll, that'll have them queueing up for a while.
