It's possible. We had a really great response to our accidental market research last spring. (Basically, we had a new production staffer that misread his paperwork and poured a whole slew of O2 toys with the wrong kind of silicone. Instead of a dual-density, they were all supersoft....whoops.)
We're also experimenting with new ways to use the supersoft material. Case in point - the new Pack n' Play toys technically use two kinds of silicone, but the base only extends up about an inch into the shaft of the toy. So it feels like supersoft but still works well in a harness. If you like supersoft, you might give the Pack n' Play toys a whirl.
