Yes! You could also change the post so all the options have a preview like you did before adding the new poll options. So changing "Quick example of this:" to "Option 4 - ... "
I like the bottom one the best (option 3) for the reason that they have different colours. The colour tells something about the community you're looking for.
A 4th option where you still have the UBP icons, but with the colours as shown in the bottom picture would be a good middleground. (Option: 'Use UBP icons everywhere but with different colored gradients')
