I know you don't want to use your sub, but IMO it is a big step down to eliminate the LFE channel, unless the movies you watch are all very talky. Having said that...
Watching movies in 2.0 can certainly be an enjoyable experience, but you are sacrificing frequency extension, dynamic range, scale, and dialog that is anchored to the screen. Perhaps most importantly, by listening in 2.0, you will not hear the sound mix as it was intended, which is a significant part of the technical creativity of many films, and not just big budget action films.
3.0 would be an improvement in some respects, with the same caveat I mentioned about eliminating the LFE channel. I do not recommend 4.0 (i.e. no center channel).
If I were you, I would consider 3.1 (no surrounds). I am currently listening in 3.1, and it is a very close approximation of 5.1. In some ways, I prefer it to 5.1.
Good luck.
