But, I could be wrong.
***. Unless I wore the kilt as everyday dress I, personally, wouldn't wear it to this kind of service. YMMV, but I just don't see any reasonable nexus between the Scottish Highlands and a memorial service for those who died in 9/11. I think it would draw attention to you and away from the purpose of the memorial.

[Edit- I just re-read this part of the OP:

In light of this fact, I think the kilt would be okay, with the same accoutrements/jacket you wear every Sunday to mass.]
