May I ask the reason why you want to combine saw with gmaw? What is the purpose of this combination?

Dear Senthil,
As suggested by other members, its not an issue to make another WPS using only two proceses (with their qualified thicknes).
In my experience welding direct SAW on GTAW root may produce burn through. I hope that you have suffecient thickness for GTAW. Minimum thickness for GTAW shall be approx 8-10mm to weld directly SAW on it.
If possible try to weld mock up to confirm the feasibility before you prepare a new WPS using existing PQR.
Regards.
CK.
