Too late to jump on Chappy? team advice pls

[bombers11]

Going with the obvious trade, Ellis (injured and B/E 60) to Crouch (B/E -1)
Tyson (B/E 78) to Chappy (B/E 53)

Still have Lachie Hunter on the pine in the forward line but with Fasolo going strong i'd keep Chappy in the Mids this game then trade Hunter out next week bringing Chappy to the Forward line.
Unfortunately i'm 6k short of Swan and all the other mids under i'm not sold on + Chappy should be a top 6 Forward and still low B/E

2 Other options are
Langdon to Crouch. Tyson to Rocky/Swan keep Ellis on pine (This doesn't leave me with much coin to upgrade Ellis to anyone decent next week even with the Hunter down grade)
or
Enright to Crouch through Langdon, field Griffiths, Ellis to Rocky/Swan. (More feasible option, downside is Griffiths/Langdon would become a starting back, advantage is with Hunter/Tyson still in team more money to work with next week)

Obviously Chappy does come with a huge risk vs huge reward tag. With 2 trades a week though picking him up might be just worth the risk.
