Ninjago COSTUME?!!?

Seriously Lego folks, you're missing the market.  WHY OH WHY don't you make Ninjago costumes?

D has moved his decision from Teenage Mutant Ninja Turtle to Ninjago.  (Granted, still in the ninja family). I've discovered that there are NO Ninjago costumes.  So I may have to buckle down and try to make one, if D keeps this as his decision.

For reference - here's the Ninjago guy D wants to be...the blue one, Jay:

There are some crazy parents out there who have crafted large helmets out of buckets and ducktape and paint and all sorts of good things - then styrofoam to make legs so that their kid looks like a Lego man.  However, my child is 3 - he will not put up with a bucket head - and will not be able to get in and out of the car in styrofoam.

So after some more research I thought, okay I can craft this...
Then I found this:

I mean, I'm not gonna do much better, right?  I should just plan on this being the costume and save myself a month of frustration and shopping, where I'd ultimately end up with something that would look nothing like a Ninjago, right?

There's still a part of me that wants him to have a Lego head.  But maybe we'll just get a Lego head container and make it into a candy bucket to drive the point home. 
Yeah.
