Ginganinja (cool name btw), you raise a good point. I'd always seen crests that were grafted and thought they were pretty cool, however I'd never considered how their vascular bundles would be affected by their irregular growth. I'd hazard a guess that if at least some of the vascular bundles were alligned with those of the stock the graft should work, but I have no idea about how this would work in practice.
