Advise on bashing lootas into Flash gitz?

As title says, I’ve bought a squad of lootas as there was a box in stock in my FLGS and I’ve been waiting months for flash gitz to come back in.

I’ve bought some 40mm bases for them, does anyone have any hints on how to make them look flashy enough? I was thinking of using the kombi weapons from the nobz kit as well, I have got a tonne of guard and tau guns in my bits box also.

Thanks!
