We've got 2 HG spaces which are vacant - if Spence comes we still have one free. I'd be very happy to sign Gordon as I think we can cover left and right wing, based upon his Everton performances, and happy to put in a defensive shift which is great.
So its definitely not either Spence or Gordon - as HG players we have room for them both, and if we don't find someone like Gordon as an HG player we are simply one player short in the squad.
Not sure Gordon has played RWB - but he does seem to have a lot of the raw attributes that would enable Conte to get him to play that role, and its not that uncommon for wingers to make that move.
But I'd be happy to bring Gordon in as a forward (who may or may not be able to trained to be RWB) assuming Bergwijn is off - that gives us 6 forwards with Son, Kane, Kulusevski, Richarlison, Moura, and Gordon.
Will it happen - not sure, doubt if Everton are anxious to sell - on the other hand not sure most of their players are wanted by other clubs. So they may need to sell
