Boots too small and seeking advice

Hi everybody, I just found my DREAM pleaser boots at the thrift store for only $30 but there's a catch there too small, like size US5 and I wear a US 7 or 8 too small 😑. I impulse bought them because their open toe syle so I can get my foot in with the back zipper done up fine, but.... my toes hang over the edge so so much 😫. The back where the zipper is, is real leather could I get a shoe maker/repair dude to add a new zipper with extra fabric/leather to make more room. The shoes are discontinued so I can't just buy them new, I could resell them but I'd rather find a way to alter them and wear them pole justfor short dance sessions. Any ideas???? Thoughts??? Thanks 💙
