Going with that blood thing I'd have it so parts of my body change depending on what type of blood I drink, so Fish blood would give me gills, bird blood would give me wings etc. It would take Nen to create ,get rid of and renew (if they get damaged) the constructs but after that they would function as any other part of my body would and I could use them with other Nen abilities like Ken, Ko and Ryu. This would have to be a specialist ability as it wouldn't really work with any other nen type.
