When it comes to bloodsmelting there are no changes as far as I know. Same process/difficulty prior/post ascension.
Im guessing you will keep the scepter as main esper so it might be handy to bloodsmelt it more, yeah. The HoV was looking very nice already but if you're gonna inherit its skill to the scepter, all your smelt work will be in vain ofc. Now isnt exactly the right time to bloodsmelt anyway, with treasure bowls going at 50-75g. You'd be wasting 25bowls per smelt medium.
