Wire repair using wire with dissimilar plate metals

What would the consequences be if I were to mechanically crimp nickel coated copper conductor wire, crimped with either a nickel coated copper crimp, or a tin coated copper crimp, to a tin coated copper conductor wire. I'm looking at big picture, the areas that we are using this is in a 30 amp max current, 10-24 gauge wire, exposed to the elements (outside of aircraft in flight.) I am thinking on terms of corrosive reactivity, and electrical resistance, heat, etc.

High performance aircraft wiring is either nickel or silver plated. Nickel plated wire is terminated using mechanical (crimp) fittings. It is never soldered. Silver plated copper wire can be mechanically terminated, or it can be soldered to silver plated fittings. Tin plating is not used on high performance aircraft wire.
