Sleeves of Many Garments & Shinobi Shozoku

[Wolfswift]

So I'm looking at playing a stealthy master of disguise Arcane Trickster character in an upcoming Pathfinder 1e game and with the Rich Parents trait I'm getting Sleeves of Many Garments to augment my disguises. Now I know they are illusion and can't mimic tactile benefits like pretending to be a Swarmsuit and actually conferring the benefits of such is right out, but as the +2 stealth of a Shinobi Shozoku is largely visual, does anyone think that's reasonable?

My GM is on the fence about it. I mentioned I could even augment the illusory Shozoku to match the terrain and practically be active camouflage, better than the original. So it seems entirely plausible it could confer a +2 circumstance bonus to stealth, right?
