Coinomi supports several currencies and ties into Shapeshift for instant conversion of coins between wallet.  Coinomi said they can add it for us for 1.5 btc, or "we" can do it ourselves if "we" can convince someone smart to take on the project (Cryptapus / Siameze / anyone?).  It could be a great way to leverage UNO Electrum.
The "how to" details are here.

Maybe a bounty of some sort is in order to make UNO happen for Coinomi, if you guys think its a good idea and a worthy project.
