species for fusion ?

[artisanoo]

I know people have successfully fused multiple figs, but can this be done with other species?
Intuition tells me maybe, because it seems similar to grafting to me - but i could be completely wrong.

The species i have in mind is citron - i have 2 citrons growing now (i posted about them a while back, one has since taken off and is almost 2 feet, but one is growing slowly. i think its pot is too shallow and it needs more room ).
in any case i was wondering if it was physically possible to fuse them?

It would probably work better if you tried to graft them rather than fuse them. But I have never realy tried to fuse citrus, and it might work, as fuseing tends to work on lots of other species.

The apple/cherry/pear family of species might work as well. This would include peaches, apricots, etc.
