So, modes are just like different boxes of the major scale...? If I'm playing C, Dm, Em, F (key of C) I can, say, start each chord out with a 1-3-5-7-9 arpeggio and then just carry on in that chord's major scale box, and then when the next chord comes, change over to it, and so on...? Wouldn't that sound exactly like the major scale, though? This is very interesting.
