The way it seems to me at the moment, if you just took a baseline plastic like dx and tried to mold their current overmold onto it, not only would it not adhere but I think it wouldn't take at all (maybe I'm wrong, but this seems more likely than not).
They'd either need to change the plastic in the overmold, use different methods, or use different plastic on both ends altogether. I think it's definitely possible, but for now it just seems a bit too out there.
The other thing to consider is what people are willing to pay for 'base plastic' vs production costs. Overmolding surely is a more expensive way to produce discs than single shots. Being competitive at premium pricing is probably already more of a challenge for MVP than companies that don't do this extra work. Further, a recycled plastic line is probably not possible with overmolded discs because they are two plastics bonded together, so another free revenue source may be out. My guess? There won't be a 'base plastic'.
If I could suggest anything plastic-wise, I'd vote for a blend that resists cold temps better than the competition. Something nobody else has really done well yet. Even in single digit + temps my soft Eclipse gets noticeably harder. In snow its as hard as my Neutrons. I'd re-buy several molds in that.
