Opinions? Using duets for solo auditions

Hi all!
This is a topic that has recently come up quite a bit among my fellow theatre kids in the process of preparing for college auditions: is it okay to use a cut from a broadway duet for a solo audition? Two pieces that came up in discussion in particular were "Some Things Are Meant To Be" from Little Women and "In His Eyes" from Jekyll and Hyde, and as for guys "Elaborate Lives" from Aida. I recognize that both shows have material that is frequently overdone from an audition stand-point, but would selections from these pieces be a more plausible option?
I, personally, have my audition cuts pretty much solidified already, but I am curious as to see what others think of this...
