Yes, and this thread is about favor items, not consumables.  I don't think that a lock-break is a good idea for a consumable anyway, as that just creates an escalating gold-based capture-lock arms race.  As a favor item, it might be 'more powerful', but it would come with the opportunity cost / potential disadvantage of not having a combat-oriented favor item, meaning that not everyone in a game (or someone in every game) would have that ability.

However, as I keep re-iterating, something like this would still need to accompany a rebalance of all existing favor items and artifacts.

How would making dozens of favor items viable with moderate boosts not be meaningful?  That would necessarily be far more significant than introducing one or two items with special abilities that have never been tested in context with existing favor items.

Either way, it's naive to think that any of it will find its way into an official patch.  If not even critical bugfixes are worthy of a patch, ported FavorMod items aren't even on the map.

Neither is more or less 'easy', given that any patch will have to go through internal balance evaluation and extensive QA testing.  The issue isn't that one is more difficult than the other, but that they're both equally unlikely to happen unless Stardock is willing to commit to a full QA cycle on a patch that alters balance.
