Vintage very-light (under low 300's, gram wise) rims are VERY soft; the tension used for modern rims will probably fold them up like a taco shell.
I wouldn't at all advise using fiamme yellows or similar for a modern rear wheel with 130mm spacing and super-high right side tension. Likewise, they shouldn't even be in the same room with a set of straight gauge 2mm spokes1
