Ok, PoPC

Phylactery of Positive Channeling

This item allows channelers of positive energy to increase the amount of damage dealt to undead creatures by +2d6. This also increases the amount of damage healed by living creatures.

Now a clever rules lawyer would realize that Lay on Hands is a form of "channeling of positive energy". In fact, 2 uses of LoH gives you 1 use of Channel Positive Energy. It seems unclear if the PoPC is supposed to work will all forms of positive energy channeling, or just the "Channel Positive Energy" class ability.

So first would the PoPC give you 2d6 to normal uses of LoH or will a pally only benefit when they actually use their channel positive energy?

I believe a strict RAW reading supports the latter, but a lenient DM might allow it or house rule it.

Second, if you were going to modify the PoPC to allow it to work with LoH and CPE, how much would the cost increase?

Strictly RAW it only benefits channeling positive energy.

To allow it to work with LOH though wouldn't be game breaking in my opinion.
