Here is the relevant info from Fernehalwes about hybrid races and interbreeding.
It's improbable, but possible. So yes, you can roleplay a hybrid and be lore-compliant, and it'll be totally fine.
That said, I would personally advise you to deliberately avoid the more common pitfalls of the "half-breed character".
Don't make hybrids superhuman (why are hybrids inexplicably portrayed as better than everyone else?), don't make every conflict into a racial conflict (e.g. Hilda's conflicts with the Temple Knights is expressed as one of social class rather than race, even if the latter does play as a factor in the former), and when you do have racial conflict, be very careful about centering that racial conflict around your character's specific hybrid.
The general stigma towards hybrid characters comes from the fact that many hybrid characters are written as fairly blatant Mary Sues who consider themselves very self-important in everything they do, who will shout about their hybrid status to the streets with a megaphone in one sentence and then angst about how everybody's racist against them the next.
As long as you can avoid that kind of extreme, I see no reason why it shouldn't go swimmingly.
