[Diomedes]

These spells are all enchantments, so all you need is the time, one mage-day per energy point using Slow & Sure enchanting.

The best way to shorten the time would be to have assistants, so you can divide the time amongst yourselves.

The other way would require finding in-game an extremely large Powerstone or Manastone, enough that you can cast with Quick & Dirty enchanting.

Really, this (particularly the sloop) would take a lot of resources and organization.
