If GW makes Perturabo come back, would you preffer him as:
1. daemon primarch
2. heavilly mutated Perty (primarch obliterator possibly)
3. regular traitor primarch.

I'd preffer option 2 or even 3. We don't need more daemon primarchs, we have 4 already - and Perty is the only opportunity for non-daemonic traitor primarch (if Alpharius is truly dead that is).
