You dont need to change the system to change dynamis. tbh there was nothing wrong with the system, it was functioning perfectly for years prior to abyssea. The reason the player base for dyna is dying is, as you said, because there is almost nothing worth getting from there for the masses of FFXI (sure every couple of people are gonna go after the relic weapons, but only so many!). In MY OPINION what SE should have done was make the rewards higher, perhaps introduce new gear and relic +2. Changing the system, in this case, is just lowering the standard: something i find unnecessary since people in FFXI are trying to get away from the over "simplified /easy post-Abyssea" world FFXI is turning into.
