unseelie fey turned to angel

[theboss]

Well i have this 20th level build 14 pathfinder fighter,2 Champion of C.L, 1 Crausder, 3 Swasbuckler. and i took the unseelie fey template. now, my question is: Is there any possible way for me to attain a PC angel and still have the unseelie fey benefits?
in addition, it'd be great if you say your true opinion on this build.

EDIT : i went for the str,dex and int build. Improved trip, and two weapon fighting.
Feats :
TWF
ITWF
GTWF
combat expertise
improved trip
knockdown
trip master
WF
WS
GWF
GWS
Melee weapon mastery
close quarting fighting

If you become an Outsider you are no longer Fey. You might gain Augmented Subtype but I have no idea which Template you would want to apply.
