I don't really think Bioware is going to make their Shepard cheat on previous love interest. It seems like Ashley would be the easiest option trilogy-wise, since she can be romanced in ME and ME3 and is encountered in an obligatory mission in ME2 (which gives her advantage over Liara, since she's only present for sidequest, unless they decide to include LoSB in ME2 movie, in which case they would probably have to split it into two.)
