Interesting but complicated. There are either too many items in houses, or a backlog of extras that still would have to be purged from the "bank" system. Keeping houses and things on graal does take file room on their servers. I do believe that was one of the reasons they have them decay in the first place.

Perhaps someway to retrieve them items up a limited time after the house falls, perhaps something like 6 months before they are completely lost. But to do so is the tricky part. Perhaps instead when your house does fall, you could turn the Key into an NPC and it would warp you to that house level one last time to reclaim your items before the house is completely lost. Or maybe instead a random level generated for your items to sit in a bit chest that you get warped to after you turn in the key. Still not so sure how that would work, considering most items are locked in chests in player houses.
Or there's the alternative, of just dumping all the items into your inventory, atleast then the items in the chest wouldn't conflict with containers.
