Mauvais said: No. That's a Rei pose. The only thing he'll get by doing this is another awkward situation with Koaru...
... But Shinji's basically Rei's half twin (same maternal genes and biological age, remember) and if you look at his character design he really has a similar figure to her so there's no reason why ha can't pull it off.

I'm sure he would be...In that way an androgynous person like Shinji was probably to his taste... or seeing as how Kaji sexually harassed Shinji in the last film it could be that everyone is gay for Shinji.

Half-sister would be more accurate, seeing as Rei is part-Yui Ikari and part-Adam. Rei and Shinji only share one parent in common.
