Since Baby Kxtten has been so well received here (and deservedly so) then (supposing she would be interested in visiting Prague, which I think is very much an outside chance, but thread title says 'just might') a US performer who has very much of the same vibe as Baby Kxtten (in appearance and general 'hardcore petite' vibe) is Valerica/Valerie Steele.
But to be fair re realistic prospects, she is pretty new and while she shares some superficial image qualities with Baby Kxtten, her performance is some way behind as yet.
As far as I can remember (I haven't searched her for a couple of months) she has done an anal scene, the standard lightweight thing (rite-de-passage for new US teens) with that white gloves/baby-oil/fish-eye-lens guy (I can't remember the name, but you know the one).
Re other relevant skills, she has done a 'Swallowed' (see screenshots below) in which she looked killer cute, and the scene was OK for a newbie.
She has done a DP for Bang. I haven't seen it and it's not an anal scene, but it proves (at the least) that she is not daunted by the prospect (I just checked out some stills and she looks like she's having fun and unfazed by the situation).
And I think (too lazy to check her bio, but I'm sure I remember it mentioned somewhere) she is petite, so this ticks a box for another thread in general tonight asking for more petite performers.
Personally, the thing I like best about her is her look, which is Baby Kxtten 'through a glass darkly', so Alt-Dark hints of and Anna De Ville and Charlotte Sartre etc.
Cue pics...
