I imagine it can be cut and reposed a bit. The stock pose has always been kinda odd, but it's more or less the same as the old macross/robotech design. The hips are fused to the torso while the legs and feet are seperate pieces, if the hip sections were cut loose they should be reposeable provide the legs are also cut at the knees.
Probably more work than I want to do however.
Without the arms attached it's very rear heavy and tips over constantly, the arms help with the balance but not by much.
