I've an Ancient Caledonia Kingussie build kilt (from Keltoi) that I have a fondness for, a mixed ethnicity background that includes 1/16th eastern Cherokee as well as german, english, scottish, flemish, french, and italian flavors, so Clan MacMutt seems like a natural for me. But I also have a family paternal lineage affiliation with the "Clan" Forrester (a late 20th century organization), modern and hunting tartans and all (designed in the late 20th century), that I should probably maintain affiliations with rather than mixing allegiances along with my lineage.

Clan MacMutt sounds like fun for those seeking an affiliation and tartan, though.
