Yes I guess it's a matter of keeping an eye on fully charged voltage per pack.

Was thinking I might try a Schottky Diode to separate the packs, like this one.

And it will handle both packs.
But even so, you're still talking 0.5v drop at 20 amps.

I don't think there's any need for the diode. It may even cause additional problems and is certainly introducing an extra potential point of failure.
The fact that the packs will equalise is not a bad thing! - you just need to ensure they do so safely which is as simple as checking the voltages before connecting them. The qualisation ensures that both packs are sharing the load and will maintain a similar charge state in use (providing they are similar type so that voltage sag under load is similar).
