Rome binders have ultra cushy straps so you can put them over your toe or wherever you like. They are designed for that, so they will probably work well. I suppose you could do that with any binding as long as the toe strap is cushy enough.
In my experience, just because a toe strap is super cushy doesn't mean you can rock it as a cap. The Rome 390 webbed toe strap is actually engineered to fit as a toe strap or cap strap. Some bindings toe straps that are advertised as "universal" still suck e.g. 08 K2 Formula.
