Assuming you are following ASME B&PV Code, Section IX, you can qualify an existing WPS with no impact for impact by using the WPS to generate a weld coupon and conduct impact testing only.

Yes, impact tested procedure can be used on a joint which does not need impacts.

Typically yes, but I believe it is possible to pick up some combinations under QW-403.5 that would not otherwise be permitted by QW-424 for a non-impact tested application.
