If you are thinking of doing mods, and money is not an issue then the R/T for sure, it is going to a long while before you get suff or good stuff for the 2011 SE. If you are just not happy with the 250 HP, want dual exhuast the revised suspension, change options and color then the 2011 SE is a great car. Gut feeling, based on your wanting a turbo kit, you may look into some performance in the future, I think the hemi will give you a firm base to build on. Even if you have to save for a few years. So I really can't see trading in a 2010 SE on a 2011 SE.
For me DWB is the only color for me, so I'll keep mine for a while. I do admit the pink look good in real life, I have not seen the Orange or Green.
