The Gay Knight in Shining Armor

Man I try to forget Preston and his barraging of my quest log. (I remember on release just walking past him lead to quest spam. Good grief).

One thing Bioware characters are known for is how they can change; hardened or softened Alistair and Leliana, Spirit or human Cole, Qunari or Tal-Vashoth Iron Bull. With this in mind I'm curious: should the hypothetical Gay Knight in Shining Armor be subject to change, or should they remain statically Lawful Good no matter what? Would a Companion who starts grey and pragmatic, but has the potential to become more idealistic be acceptable? Likewise, would a Paragon whose weary life and particularly brutal Personal Quest that could harden them be too much?

Finally getting a gay KISA only for them to inevitably become cynical by the end would be a huge Do Not Want for me, but there are a lot of other ways they could develop. Like growing into a more mature and nuanced idealism, being more aware of how others and their circumstances may not fit neatly into their code and how to deal with that, letting go of some prejudice(especially if it's internalized!), moving past some fears, doubt, or pain that have weighed them down(but done while preserving the KISA's agency in that matter rather than having the player "fix" him on their own), getting past an unhealthy need for approval and thus becoming less susceptible to following bad orders, trusting his own moral compass over a strictly dogmatic approach, etc.

Hell, even a "coming out of the closet" story would be fine if done well, though I'd hope he would have more going on than just that.
