You really don’t want to go down this road. I have no problem starting a movement to get Americans to call them “LEGO’s” and you won’t be able to even suggest it’s wrong because it’ll just be a contraction of “LEGO parts,” “LEGO bricks,” and “LEGO sets.” (But feel free to lambast us over punctuation and quotation marks.)

That isn't how contractions in English work – you can't form a contraction from two nouns.

Quite right, what's needed here is a portmanteau - Legarts

I prefer Legricks. Dammit kids, pick up your legricks, I darn near killed myself!
