12' x 11' room with wall of windows

I am considering a dedicated listening room and the only thing I have available is a 12' x 11' room with 8' ceiling and one of the walls (that I would likely have to put my speakers on) is 95% windows (Bay window actually so the room isn't an exact rectange). I have my heart set on the Dynaudio C1's and simaudio I-7............... Upon further reflection it seems that due to my room constraints I may (more like definately...) be wasting a lot of money for nothing. I am looking at picking up the gear as demo/used but it is still going to be in the ballpark of 15k when it's all said and done. What do you think? Should I abandon my project altogether and improve my current HT setup ( 14 x 15.5 x 11ft ceiling)or go with the listening room anyway
?
