Correct me if I'm wrong, but as some of us have made Add-Ons that plants bricks: wouldn't it really be possible to rewrite most of the planting mechanism to work in a similar matter? The biggest issue would of course be backward compatibility and problem with other Add-Ons, but other than that, there shouldn't be that big of a hurdle to pull off?
I might be wrong in how fxDTSBrick::plant works as I have rarely used it.
