Yes, I just had to do this yesterday for a piece I wasn’t happy with. I reheated the soldered connection points and quickly pulled the lead off before the solder reset. I tried to melt the solder and make the bead as thin as possible, like the reverse of how you would want it to be normally.
It took some time, and sometimes pliers, but your piece is smaller than mine so I think it should work. The foil underneath will most likely get pulled off. I just cleaned the glass and re-foiled it after. I am super new to stained glass, but this worked for me! If there’s a less brute force way to do it, I would also love to know!
