If it was something Parian could do, then I'm pretty sure that Garment could manage it. I suppose there might be something to the weirdness of her expanded power from Ward (as far as I know it's something to the tune of could always do, but didn't), but I don't think she'd really be able to separate Joe and Tetra. Or rather that if she could be used to do so then Garment under the direction of the duplicates could manage. We know that Garment has up till now been able to over power Tetra whenever it came to moving her away from direct contact with Joe, but at this point it might be a case of fearing causing too much extra damage or Tetra just being too damn strong thanks to all the divine blood she's been drinking.
Technically parians power is controlling dead skin cells and hair, her power wants her to use human skin and hair, but that is something she doesn't want, so she doesn't. The reason why Wildbow said that she's super powerful is because her power is used to essentially make a pseudo Endbringer made of dead skin.
Which is why I'm glad she didn't do that.
But ye, Garments power can't do that.
