until they improve and remove all the terrible flaws with the actual ignite, even contemplating a port is a bad move
You wouldn't necessarily need to port anything, just create the basic functionality of Ignite in a mobile app.
Without the need to scan for games or download them, they can easily integrate a mobile app with the Ignite login system, ignite access tokens for the loot box, and allow access to the message system, billing system, forums, sb, news, etc.
Actually, minus the loot box, this sounds almost exactly like what you can do with AeriaMobile.com
I looked into the possibility of doing a custom app, myself, but I don't have the keys for the Ignite login system
