need more lift when I switch to a dry suit?

Only reason I asked is that the choice of Trilam over Neoprene can affect buoyancy characteristics if there is a full flood. Another factor in choosing adequate wing lift capacity is how much of your weight will be ditchable.

Everything except the backplate would be ditchable, at least that's my plan.

No, you don't need a bigger wing for any single-tank rig. If you went to something like LP85 steel doubles, that would be a different story.
Shop just wants to sell you a wing.
I dived single 95's and LP 119s with a 32lb wing and drysuit and had plenty of lift with 4th element arctic and xerotherm layered undergarments. In 38-40 degree water.

Again.... it would/could matter if your backplate is SS, Aluminum or Composite.

You don't need ditchable weight or a bigger wing.
