I am stumped on another project (oh wow...again

So I have this request for a bowl. Easy enough.
But they want a piece attached to the side of the bowl (I haven't even got to the auctual placement of the piece yet...still trying to figure out how to attach it..)
Let's say it's a leaf, so it would be a slumped bowl, with a leaf attached to the side of it. The leaf wouldn't be very large, but how to attach it?
I would like to make a lampworked leaf, but I'm assuming it would be easier to just make a fused one for attachment sake...
I was thinking...slump the bowl and then attach the leaf with a torch..to make the connection. If this isn't crazy, then would I have to "preheat" the bowl so it wouldn't crack when I apply heat? Would the attachment even work like this?
Or...I was thinking slump the bowl and then fuse on the leaf in a second firing...but how would you get the leaf in the right position to fuse--would regular fusing glue hold a somewhat heavier (but not to heavy..) object? Would fusing a piece on change the shape of the bowl?
Ahhhhh !!!
I'm going to experiment for sure, but any tips or suggestions before a couple of these go down the drain would be most appreciated if you can help! Thanks again,
Sarah
