Yes, another way you could enchant it is to first cube it to Lv5 or so, then the option reassigning will be easier since there is much less difference between a good and bad enchant at a lower enchant level. From there, you could then puzzle it up to Lv10 as usual. The only drawback is that you would have less dura in the end for resupering.
I've never done it that way myself, but I would say it's viable. It's your choice in the end.
