Untradeable Player Swaps?!

I'd love for EA to produce a market where players can swap untradeable players with each other. 

I've been doing lots of thinking and research on this idea and here are some thoughts I'd love the community to have a think about.

Untradeable payer swaps is a concept where we have a separate market not reliant on any coin based trading where players can simply swap any Untradeable player with another. 

Now we all love the concept of the transfer trading where we can save up coins and buy our favorite players but wouldn't it be great if we could remove the idea of players being traded based on coin value and have a separate market where people who want a certain player can offer up untradeables as a swap. 

With players only being able to swap players who are untradeable this would incentivise purchasing untradeable packs and doing SBC's, further to that players who later build a team would be able to swap for players who are no longer in live SBC's 

It would be immune from any sort of cheating as you can't use players purchased with coins etc so you wouldn't have the websites trading players for coin buying. 

And further untradeable player swaps might enable the players who don't have millions of coins to have a player they otherwise wouldn't be able to get. 

Just a thought and hopefully we as the fans get this.
