Personally, I don't see the point of yet more item rules. So I say, craft whatever you want!
I think all WOTC items are kind of meh, now that flaming holy weapon which confers fire and necrotic resistance called Bahamuts Blessed Tooth which will transform in to whatever the users primary weapon is.... now that one is rare or actually unique or nonstandard - see references in phb.
My favorite rule is dont be a nit with multi items.. I dont use generic components .... if you make too many of a specific item you will end up not being able to find the items ingredients or they become horribly expensive ... ie economics.
