I did something like that whit a piece of drifwood, initialy it floats but as said soaks and sinks after a while. You actualy need quite a larger volume of floating material to create enough buoyancy to keep the soaked part up, that spoils the fun. Also if you just like it floating it will float around and go with the flow and maybe end up in the opposite corner you like to have it. And over time get top heavy and turn over on you, upside down.

I took 2 little sucker cups, placed them on the outside of the tank in the corner i like it to have and stay. Bought some 0.6 mm dynema at the local anglers shop. Denyma doesn't rot over time and doesn't snap, you need something realy sharp to cut it. So any movement or rubbing over the glass edges doesn't damage the dynema. I secured the drifwood with this thread at each end to the suckercups. If you buy it in the anglers shop the color will be Army green and since it is 0.6 mm it's nearly invisible so it doesn't distract the view.
As long as your humidity is high enough for the plants in question and your water is rich enough in firts, you can put anything on it you like. You just need something for the roots to grow into. Sphagnum is ok, but living sphagnum is hard to keep alive in our parameters, dead sphagnum will slowly disolve. Best is life moss which likes to stay alive and dosnt mind to grow emersed as well.. My piece of wood is like a holowed out tree trunk, like a canoe. I stufed the crack with Ricia Fluitans and it worked out great, the Ricia attaches to eachother and is growing out and creating a floating island around the wood. Did put HC in there and that's doing realy good, it likes it very much emersed, doesn't even need transition from sub to emersed. also got UG in it, but it seems Ricia and UG don't mind together but the Ricia is so hungry it competes with everything else and UG slows down it's growth. Got staurogyne repens on it and this also doesn't mind being there, slowly grows towards the surface. Also got a few stems of Rotala Mexicana goyas growing up there. And that's a funny one, it started out with very small young cuttings and it realy refuses to grow emersed, it just kept creeping till it reached the water line and than dives under the surface and happily grows on. Also experimenting with mosses on it i find in the forest. Some with succes others not so happy.
This is how it started.

This is how it looks now when i do a water change.

It's doing great and love the idea even more than the day it came to me..
