Here's a house rule I'm probably switching to, which has the desired effect at low tier (while also preventing some cheesiness of using an item's daily then swapping in another type of item)
Daily Item Usage tracking
Replace the usual Daily power limitations on items with
'Using a daily item power prevents the use of any other magic item in that item slot until you take an extended rest.' and'Using an encounter item power prevents the use of any other magic item in that slot until you take a short rest.'
Example: A level 4 character with a Frost weapon, Dwarven Plate, and a Cloak of Resistance can usually use 1 of their dailies, plus an additional 1 at each milestone. Under these rules, they could use all 3 of them, but they could not acquire additional dwarven suits of armor to swap into for extra healing surges.
Why: Mostly for player sanity. Preventing someone from carrying a dozen suits of dwarven armor in a bag to get extra surges is good, but making people track the powers is somewhat annoying and can lead to players favoring passive equipment bonuses rather than more interesting power uses.
