Recon they will do fine.
I use brass bead making ones from the ROC, they are smaller diameter and thinner, about 2mm long. I have to ovalise them to get 2 strands in.
I bought them originally for pigtailing components in, they crimp easily and solder beautifully. Can't remember exactly which.
Something like:

Other suppliers and makers available, this is not a recommendation etc.
