Lootable Spell Factory

I believe that the Spell factory should either be lootable, and/or drop all spells/explode, throwing spells everywhere when destroyed. For example, if an attacker were to destroy a spell factory filled with freeze spells, it would throw freeze spells around the map and freeze attacking troops, allowing a few to be picked off by defenses. however, if a fire tower were to fire beams at these frozen troops, it would dethaw the troops, but in the process progress to its most powerful beam.

what if they are jump spells in this? you help your enemy? and does it take the spells away from you? and why should it be lootable? what kinda loot would it drop (elixir, DE, gold) and how much?

please add more details as this is not very clear.
