Shane,
You need to determine what the min impact energy required is. If the results comply with the min required you're good to go.
Establish the max heat input for each process. That is your max on the WPS.
As for HAZ's match them with the weld process locations and use the results in the same manner you used the result of the weld test. In other words, you should have HAZ data that is the same depth as your weld process, for example GTAW, the same depth will be your GTAW HAZ.

Shane, I do not think you are off the mark with your statement about higher heat input/higher deposition rate as long as you are considering similar thicknesses generally.
I have a few questions;
What is the material specifications & grades, properties and consumables used (including manufacturer)
What is the actual thickness and has it been post weld heat treated (can't remember all the previous details).
Is the design code ASME VIII or EN 13445 (or God forbid some AS/NZ standard that doubles up for shearing sheep)?
Any additional owner requirements?
With impact results the norm is that, for each of the three values at each location, you determine the average and note the minimum and check to see if these meets the requirements of the standard/code. To the American standards, and I am sure I will be corrected if I am wrong, you must meet the base material requirement at the MMDT (or if not specified in the standard the owner must give the requirement). Impacts are taken from various locations, eg cap WM and HAZ (+2mm +5mm), root WM & HAZ depending on which standard/code you are working to but I think I am safe in saying you do not add them all up and take an average overall(as I have think you have done), never seen that.
