The only viable solution is to run the higher level challenges with higher level toons and then bank all the mats for your lower level toon. I don't think this makes any sense. If we're making a level 8 item, and we want to upgrade it to tier 2 or 3, we shouldn't be required to gather level 15 mats. Upgrading a level 8 item to tier 2 or 3 doesn't raise the level of the item. It's still level 8.
I think this needs to be re-examined. If one wishes to upgrade an item to a higher tier, then one should be required to gather the same level mats as one gathered to make the item in the first place. If the price for this is to make the minimum level of the item increase I can live with that. The same thing happens with Mabar and Crystal Cove items anyway.
