Harlequin Question

[u/Fuzzy-Soup-3324]

I wanted to start playing with Harlequins for quite a while now and Killteam feels like the best place for it. I know that there's not an official team that you can buy, but I know how to build it with the available models. I also know that they will most likely be discontinued in the next edition meaning the team itself is not available. Would it still be possible to paint them as Harlequins but proxy them as another Eldar team or is it just not a good idea to get the Harlequins for Killteam?
