I'd vote "no" to these changes.
Adding HMP/cinders etc. to Aby NMs would result in those NMs being locked down by gil-farmers, making it almost impossible for a person to build an Aby-stage Empy. I think adding those items to other battlefields HKCNM etc is a good idea, although I doubt SE would do that, since they just added those items to Ambuscade and had previously "no plans to add those items outside VW."
SE already made Aby-farming easier, when they added trigger KI to gold boxes. In the beginning this did not exist. Also they added Trusts to Aby recently. Also they removed the big KO moves from Glavoid etc. Also since ilvl gear arrived, mobs in Aby can't really hurt you, and you can solo-farm mobs and NMs very quickly and easily. Also it seems that in 2016 proc KIs are more likely to just drop anyway without a proc, than they were in the start of Aby. Also they made it so you can buy weapon skill-ups using Sparks Books, so you can cap all your proc weapons very easily now, compared to 2010.
I farmed five Empys past Aby stage for myself, and helped LS member farm another 30 or so Empys past Aby stage. I did those Empys from 2010-today, and noticed how very very easy it is to farm Aby-stage Empys today, compared with 2010-2012.
My main is WAR, and I could solo 50/50, 50/50, 75/75 in under a month, on WAR/THF, before Trusts were allowed in Aby or even existed. It is really not hard work.
Basically, levelling a proc job such as WAR, and capping a variety of weapons, is part of Aby. Aby and VW are also the only places where WAR is still considered useful.
Should they remove the "tedious" Relic Weapon stages where you have to kill mobs with WS too? It is a slippery slope, when you start changing the fundamental existing systems for RME. Where to stop the easyfication? Most of the recent changes to RME have been related to removing time-gates on entrances for RM, and making the content easier to get access to, for example free cruor/stones/atmas and Trusts for new players in Aby. Changing the actual nature of the boss farming would be a new step really. I think the game is losing a lot of the skill-element, removing the need for Empy procs would be another step in this direction.
Levelling multiple "toolkit" jobs, and capping all the weapons, is part of what made FFXI awesome. Using those WS at the right times, getting a proc, is a fun mini-game. Completing your Empy <This way.> is a sense of achievement, you accepted the Aby proc system mini-game, you tooled up correctly, and you beat the game system. Equals feeling happy about beating the game by the existing rules.
