You'd only need to remeld the remaining 4 accuracy. It's cheap, only 4 Accuracy I's lol. - though you'd need to buy another Sphere Scroll with Soldierys, and get 4 Alexandrites again. I'm currently in the process of removing 18 accuracy from my Relic, but I'm going to do it in chunks, as the Soldiery Cost to keep buying new Sphere Scroll is gunna be pretty bi g:P
