Here are many loads from published data...

You could actually load the 10mm with data from the 40S&W data for lighter loads.

Yep totally agree, 40S&W load data is fine in revolvers.
Maybe you have done this already, but you can have her try some cheap 40 S&W boxed range ammo before loading mild 10mm.
I have shot 40 out of a 4" 610-2. It's easy to shoot plinking ammo. Just like shooting 38 Special out of a heavy N frame.
+1 on the 40S&W for mouse fart loads.
10mm shoots relatively heavy bullets and has a relatively large case. You'll want to keep your chamber pressures up above 15,000 psi to make sure the powder burns cleanly, therefore you should use faster powders. Of what you say you have I'd recommend TiteGroup, Red Dot, Bulls Eye, or Clay Dot (Sport Pistol works well too). You won't find hand gun data for Clay Dot since Alliant says is only for shotgun, but they also say it mimics Hodgdon's Clays, which is a poular handgun powder. I use a 165 gr lead bullet for competition with 3.5 grs of Clay Dot which make a 125 PF; you can go lower; the same load of Clays gives similar results. Both are touchy powders, 0.1 grs can make a 40fps increase in velocity, but it burns very clean. I've used TiteGroup, Clays and Clay Dot in my 10mm revolver for softer loads, they all accomplish my goal.
I would go with 5.0 grains of titegroup with either the 165 or 180 grain. Should be well above 15K psi with either bullet, but won't exceed about 25K psi either.
