top and multi-graft?

[shaneatwell]

I have well established, mostly healthy dwarf lemon (unknown cultivar) that produces too much lemons for us. Also, I'd like to get more citrus in my yard but don't have enough room. Does it make sense to top the lemon and multi-graft it? Or am I tempting fate? Is it going to grow too aggressively? The shoots I get even after minor pruning are already pretty aggressive.

Best would be to go for lemon on bottom and something else on the top. Won't be a pretty tree but will
work.  I had many multi-graft trees at my old house before I moved. See my site near the bottom for a picture of how
it might look: https://sites.google.com/site/mrtexascitrus/home/citrusvarieties
