OK, let's be concise here.

Untrue.

Completely and utterly untrue.

Untrue, and I mean, really untrue.

Pearce's writings give a date of 1900, so, technically, that may place the concept of the Irish kilt in the 20th century.

Again, untrue. The Scots did not get tartan from the Irish. There were solid color kilts in Scotland, but I would not describe them as commonplace.

It's probably unpopular to say these things on here because they are not true.

Again, untrue. Kilt wearers can be seen everyday in Scotland that are not connected in any way with piping or weddings. What a heap o' kak.
If you have any evidence to the contrary, please post your academic references. Most of what you say appears to be in opposition to established Irish and Scottish history, so you may well be breaking new ground.
