Gloshei,

You could definitely work in beaded cross stitch if you choose. Keep in mind that beaded cross stitch will leave your beads on a diagonal slant, though if you're working large scale, that probably won't affect much, since the more beads you have in your project the more coverage you'll have and the less the slant will be obvious. Still, it may be something to consider. You might perhaps want to try something smaller to see if you're happy with the way the slant of the beads look before you tackle something larger. Also, with cross stitch you'll want to consider your fabric carefully, since the cross stitch fabric isn't exactly the same shape as your beads, so some of the fabric could show through. (Definitely use the same color of thread to apply your beads as the fabric, so there's less to show through the beadwork. Again, I'd suggest trying with a smaller scale image, perhaps a small cross stitch pattern made in beads, so you can see if this is what you'll ultimately like. )

I think it's wonderful that you're willing to think outside the box and consider options beyond traditional stitches!
