There is precedence in modifying the surcharge's cost for special cases - notably, Affects Others applies to both the base cost and the surcharge - so I could certainly see applying the same effect here. I don't see anyone with, say, an Alternate Form that gives them a [+100] template considering it to be worth it to apply Costs Character Points if this only discounts the trait to [93] instead of [105], but I could see someone considering it to be worth it to discount it to [21].
