Switching relic weapons

[Siniroth]

If I have a Rogetsu sitting in my inventory (stage 3 katana), can I start building an Annihilator without finishing Kikoku?

just trade the relic gun to goblin, should be fine?

I've gotta collect it first, at work so can't do that yet, figured I'd ask before bothering to hunt one down and bring it up to zvahl with all the stuff just to have him ignore me

The 5 Stages
Each base Relic Weapon can be upgraded four times before Trial of the Magians. Three of these four upgrades are handled by a Goblin NPC named Switchstix, who can be found in Castle Zvahl Baileys. Each of these three upgrades requires that you simultaneously trade him your current-stage Relic Weapon along with whatever materials he asks for. Switchstix will then ask for his commission in Ancient Currency; this is a separate trade, and the upgrade process will not begin until he receives it. Your Relic Weapon and materials cannot be returned once traded. Furthermore, no other upgrades can be performed until the Ancient Currency commission has been traded to Switchstix. Time needed for the upgrade process varies by stage; when the waiting period is over, speak to Switchstix again to obtain your upgraded Relic Weapon. The specifics of this process can be found below.

Make sure you havent committed to a currency trade

Since thats obviously directed at me
If hes traded stage 3 to gob, my understanding of that quote is he will have to go to stage 4 before gob does anything else.
