Safest way would be to see if you can find some Flex Pin speaker connectors.
They were designed to take 12ga down for older style screw/punch terminals and such. Not certain they'll work with Aton's connector though.
I am not 100 per cent with you. It will depend on whether the speaker terminals are spring type, binding post, or...
A pin may only get 20-30% contact with some amp connections. Worst would be one of those spring loaded terminals where it just has two thin pieces of metal clamping the pin. In that case, stranded wire would get a whole lot more surface area actually connected to the terminal.
Ernie's on the right track. There is no resistance increase with the short change of gauge. In similar situations I have "pruned" a stranded wire until it fit by removing only as many strands as needed.
