I'm confident that the metals should mix sufficiently by themselves
assuming they reach melting point. Accuracy is not too important for these
purposes.

Reckon this sounds viable on a backgarden scale with limited budget?

It doesn't sound viable to me. My experience with molten metals over the
years tells me that the metals, assuming you achieve success in melting them
without a fire, are unlikely to become a homogeneous alloy. They have
little reason to unless you give them some type of stirring action. When
melted by induction in an inert atmosphere, the heating method serves that
purpose. Unlike gasses, metals do not always distribute themselves
evenly when combined, although they will do so when assisted. Some metal
combinations will stratify given the opportunity. Silver and iron, for
example. You're also going to have to come to terms with the fact that iron
will be absorbed by the molten metal. Dunno what affect it will have on the
purpose, but it's not a good idea when melting aluminum for casting.
