Wrote an essay in response to this as to why I think these could be gettable but it errored and I can get it back.

I’m not doing it again so in quick terms I’d go for the following 
Tedesco, Fletcher Sharpe, Laurie, AJ Brimson, Tom Chester, Jye Gray. 

Re Tedesco - Wigan haven't signed a player over 30 from the NRL for a while and I think that's a good policy to have.

I appreciate Wigan have tended to not sign 30 plus NRL players but there have to be some exceptions. 
Tedesco would be one of the biggest signings of all time in SL.
He’s still in the top 3 fullbacks in the NRL is the ultimate professional and has a great injury record and is a natural leader. 
I think he will sign 1 more year at the Roosters and I don’t think Field will be going anywhere.  After the 2026 season though I think he will be heading to SL as I don’t see him playing for anyone else apart from Wests but they have Bula who is very much the future.
I do think Catalans will be keen on getting him for 2026 but I expect this is going to be a tough year for the Roosters with them investing heavily for an assault on a premiership next season which I think he will want to be a part of. 

i didnt think they could be our marquee based on the wording of the marquee types, but have had another read, and it only says that at least one must be federation trained, so it a case of the accountants working their numbers to work out which saves us most on the cap. So my initial understanding was that we were allowed one of each of the below, but by the sounds of it, it could be 1 * fed trained and 2 * non-Fed trained

home grown  £50k on cap- so club trained i.e Faz, Smith or Nsemba
federation trained £100k on capi.e. Wardle, Thompson 
non federation trained £150k on cap i.e. Field, French, Ellis
