If I understand correctly you're suggesting that LV makes a scalar transformation prior to legalisation checks/cost model analysis? If that's the case then I don't think we can do that as this is beyond LV's remit and I don't see how that's any different to making a scalar transformation in a separate pass prior to LV.
