The plan isn’t to increase inventory size, but ultimately for us to move hard-baked items (cosmetics/items that cannot be customised) to a different storage solution (which is what we did with illusions already). It’s just taking a bit of time.
We don’t expect everyone to have just 1 of each weapon type, but if they did, they’d have around 7% of their inventory taken at most (in the case where everything but weapons was removed from the inventory storage). In the situation where every item is removed apart from weapons, a player could have 13 of each type before they hit the cap (with every weapon available in the game right now).
This is napkin math though, so approximations 
I can whip the deeds out of your inventory should you so wish 
No ETA for the storage refactor yet though.
