Complimentary Skill Rolls for Influence

[Yenaldlooshi]

In reading Exploits pages 6 and 10, I am wondering if it would be wrong to allow a player with many of the skills for influence rolls (a bard) to make additional skill checks to try to add to the success of a master skill. Example; rolls using Diplomacy with a roll for Fast-Talk and Sex Appeal as complimentary skill rolls per Exploits page 6.

Though the text states; "This usually means rolls against two different skills, attempted by two different delvers...", the word "usually" gives flexibility for this and since the skills seem combinable in many cases. ie. Using fast-talking with sex appeal at the diplomatic bargaining table should be a thing so I am thinking of allowing it.

Can someone make a good case not too? Should I limit it to only one complimentary skill roll per attempt? (I just noticed how busking works on page 14 so I think I will run with just one main roll with as many complimentary skill rolls as appropriate to the scenario)

I don't see this really encouraged nor discouraged by the rules (unless I am missing something).

What say you all?
