MTG Salvation

Hey all, I'm looking to build my second Modern deck very soon and I'm really digging the Deadguy Ale style of play. My first deck is Jeskai Geist, so I do tend to lean toward the Midrange game plan as it is. My problem's lay in my budget. Liliana's and Marsh Flat's are a little rough, especially the Lili's. I already own a set of Strands and Deltas, as well as two Mire's and a Flats already. So is there any way I could work those fetches in, obvious running the singleton Flats with a mixture of Strands/Deltas? Would that be feasible until I can get the rest of the Flats (if it works ok they'd be close to last).

Also, is there success in the deck without running the Lily's? What would a Lily'less deck look like if anybody would be so kind?

Thanks for any and all help! I'm dying to start putting together this deck.
