For examples, I'm wondering if either the Grizzly G0555 or the
Delta 28-206 are up to the task?

Theoretically yes. For those saws, get a Woodslicer blade, and you will ahve to
go slowly.

In the end, it's like using a Sears benchtop tablesaw over a Powermatic 66 or
Unisaw. While they do the same job, some do it faster, or with greater
accuracy.

You basically want to take some very deep cuts from a hardwood and expect them
to come out reasonably smooth, with little deflection.

The bigger bandsaws exist for that sole purpose; they allow you to adjust the
tension properly for such heavy duty cutting (and resawing something 10" high
is very major duty). If that is what you want to do on a regular basis, then
you really want the MiniMax/Laguna/Agazzani type saw. Because if you are doing
a lot of this type of cutting, you want the Lennox Carbide blade, and the
25,000 psi of tension the blades require (and the high end Delta 14" bandsaw
will give you about 14,000 psi if you use the Iturra kit to increase tension).

You might not save money, since you will probably produce a lot of veneer that
will belong on the scrap heap, if you do a lot.
