Maybe. Traveling for one week and three months isn’t all that different. There are only so many things you actually “need” to survive. Will you be washing your own clothing somewhat often? Do you mind wearing the same clothing for a few days in a row? Will you be buying or collecting things while traveling that you’ll need to carry with you?
Start by looking at this in the reverse of how you asked the question. Rather than ask, I own a GR1, can I fit everything into it? Ask the question, I have this much stuff that I need to bring with me, does it fit into my GR1?
Packing should be an inside out process. We have items, X, Y, and Z that we need to bring with us. How big are they? While we’re there we want to buy items A, B, and Z. How big are they? Does the combined volume of items A, B, C, X, Y, and Z fit into the GR1 or shall I choose another bag?
If you figure out what you’re bringing and you want to share it with everyone send us a picture and a description and we’ll consider sharing here.
