That's quite a shopping list. I agree that some of those options would be great, but 10 new signings - phew! We'd be relying on some loanees in that lot.
Also, you have to get rid of some players - we've already signed up Long, Hall and Stevens. Who goes? The likes of Hanson, Forde, Mousinho etc are still here. To bring in some new players, we may need to pay up a few contracts/transfer list some players.
For me, get right on the model that works for us - shop for the best young talent in unfashionable leagues (Sykes, Whyte, Marvin Johnson, Gorrin) and the PL/Champ released players looking to rebuild their careers (Brannagan, Lundstram, Dickie, Moore, Ledson). If ticket revenue isn't going to be coming in, we need cash from elsewhere and only through player trading can we generate it. Cash in on Brannagan and Dickie now and use that to see us through 2020 and invest some in bringing that talent in to develop. Even more so, why not find another 'keeper that way too?
With cash flow soon to be a problem for all clubs, we need to prepare behind the scenes first.
