Unusual Class Variant (dragonscale husk)

[TobyFox2002]

Is there a way to do a class variant that that requires not a class but a class feature. I've run into an issue coding problem trying to get Dragonscale Husk to function.

It doesn't require a class but the ability to wear Heavy Armor.

DRAGONSCALE HUSK

Any warrior knows that skill in battle isn’t enough; you must also guard against the attacks of your enemies. A well-forged suit of armor can mean the difference between life and death, but a warrior whose very body is his armor has an immediate advantage.
Those who have the blood of dragons running in their veins can gain this benefit.

Class: Any standard class that grants proficiency in heavy armor, such as fighter or paladin.
Level: 1st (unless the class grants proficiency in heavy armor at a level other than 1st, in which case this feature can be taken only at that level).
Special Requirement: You must be of the dragonblood subtype (see page 4) to select this alternative class feature.
As long as you gain the dragonblood subtype at the same level that you would gain heavy armor proficiency, you can select this class feature, even if you would normally choose class features before selecting the option that grants you the subtype. For example, a 1st-level human fighter who takes Dragontouched (see page 18) as one of his 1st-level feats could also select this class feature.

No. Unfortunately, a class variant has to have a class to replace or it won't work. To do this you'd either have to make a new class variant for every possible class this would work with or find an alternative. A template or a trait might work.
