Maybe a silly Avocado grafting question

[kingoceanos]

Has any one tried grafting a smaller type of avocado tree to root-stock and then a larger type to that to see if it would influence the larger types full grown size? I am thinking of something like zutano seed with a Lila cleft graft (no buds to push) and then a Fuerte cleft grafted to that. The final tree being a Fuerte, hopefully influenced by the Lila to be a smaller tree.
Thanks

Commonly done with apples, pears, roses, etc.  See interstock or interstems for usage and benefits.

I don't know the answer off the top of my head, but I was interested in something similar, namely grafting the same alternate bearing variety onto 2 separate parts of the tree in consecutive years, with the idea being to test if the alternate bearing phenotype is being driven by a treewide phenomenon or if it is branch/graft specific.

My understanding of avos is that dwarfing effectsbof Rootstock are not so significant. I don't know specifically about interstocks but by inference it seems like the growth habit is dictated by the growing portions. 

I think Carlos tried an inversion graft on YouTube to try and force early flowering and slow growth as well but iirc it killed the rootstock.
