You're asking about proposing as in marriage, or proposing as in asking for a second date?
Marriage - sheesh, not yet! Second date - sure, ask.
And a kiss on the second date would be lovely, and is possibly welcome, but recognize that you dazzled her on the first date in a very out there, different kind of a situation. Maybe make the second date all things that she wants to do. I see that first date as being extraordinarily one-sided, on the side of things you like, that are about you, that scream you, you, you
Find out what she'd like to do, and do it, and see how things go.
