How far into the batch are you? Have you mixed the oil & lye yet and reached a decent trace? If so don't worry at all. You can just put the lid on your crockpot and let it sit overnight then zap test in the morning. I think this would work even if you used all water to dilute the lye instead of a glycerin/water mix.
You can prob still make it work even if you haven't blended the oil/lye to trace yet. If you have a stainless or silicone whisk, you might be able to use this as an alternative to the stick blender if you have patience and enough arm muscles
When I make liquid soap, I use equal amounts water & KOH then add 2x the water amount in glycerin. I add this mixture to the oils melted in a crockpot and stickblend to trace then switch to a silicone whisk. Usually it goes pretty quickly from whisk-able to stiff vaseline that needs to be stirred with a heavy duty spoon. At that point I turn off the crock pot and let it sit overnight to finish saponifying.
