Using 3.5 skills in PF

[Quatar]

Hi

My GM houseruled that we use the 3.5 skills in our PF game, yes that includes 4x at first level, max rank of level+3 (or half for CC). (I think it's a horrible idea, but what you gonna do?)

Now adding the new skills is a bit tedious but I can do that with the Editor I guess. The extra skills points at 1st are also done easily as its just a 1 time thing.

But three things:
Is there any way to allow max rank to be level+3 without throwing errors out left and right?
Is there a way to delete skills not needed anymore like Perception from the list? For that game only not permanently
Is there a way to make CC skills cost twice?

Or has maybe someone done anything like this before and could point me to the link where to find it?

Alternatively I do my skills in an excel sheet, so they're calculated correctly especially when it comes to CC skills and then just edit the numbers manually in and ignore the warnings. Might be the easiest way.
