[idea] Using normal frame parts to substitute some prime resource cost

[dual1020]

So with some players discussing about how expensive it is to craft vauban prime, most notably the nitain and oxium. An idea popped in my head for vauban prime and maybe future primes: Why not use normal frame parts (or an already built normal frame) to substitute or reduce the resource cost of crafting primes? (and vauban prime)

The reasoning is that when vauban prime was announced, i humored myself with the idea that vauban prime would require normal vauban parts as a crafting requirement. Since vauban is a frame who's parts could only be obtained through alerts and is pretty rare, a prime version of vauban requiring normal vauban parts would suit its rarity theme and because i myself have 2 sets of vauban parts laying around, but was surprised (or to anyone else: not surprised) that it required resources to build.

It conflicts with lore since primes came first
