Based on game sim, will Taranto more of a high hf role like a Toby Greene and pinch hit in midfield?
Based on the match sim. It looks like macca might be used on a wing? I'd happily give him a chance inside.
That said , I'd go -
Banks. Miller. Brown.
Balta. Vlastuin. Trainor.
Grlj. McAuliffe. Hotton.
Taranto. Lynch. Campbell.
Lalor. Faull. Armstrong.
Nankervis. Smillie. Cumming.
Algar. Sims. Gibcus. Rioli. Hopper.
Retscheko. Trezise. Mansell.

Yet I question how realistic this is with; prestia. Hopper. Taranto. Ross. Grlk. Cumming. Lalor. Smillie. Hotton. Etc.
*At this stage*
Good teams don't tend to rotate too much:
Neale, Dunkley, Mccluggage 70%+
Ashcroft W 50+%
Martin. Cotchin. Prestia. 70%+
Bolton. Edwards. 50%+
(2020 season)
The smillie injury won't matter in the mid-long term.
Hotton was apparently BOG, or there about playing in the guts.
The coach is obviously high on the idea of lalor. Cumming getting time there too. Hotton/Lalor etc. Should play forward but it's unlikely that's where the coach wants them if they come good in the big picture.
Hopefully Grlj is good enough to push for that position.
Taranto is 28. He is still going to get many mins inside even if used forward more.
Hopper not being versatile complicates matters too.
Best case is

Richmond have 5 younger more talented mids than macca who will be A grade and need time playing midfield proper.
Then you have the next tier like Campbell, Rioli.
The likes of sonsie and macca are going to need to play other positions too
