I believe you could do that. However I’m not too familiar so I could be wrong. I’m going to have to tag @RokuKariza-D, so that he can explain to you more about it.
EDIT: Actually I’m correct. See below post.

Thanks much. The process went smoothly
@Weary sorry about your loss. When I lost my father-in-law, I lost a real buddy. It's been over 7 years and it's still tough. Lost my mother-in law almost 20 years ago, and yes, losing her was a huge loss as well.
Thank you for your kind words. I remarried at 59, and my last parent died 12 years ago. It's been a blessing to have parents again this late in life, and my father-in-law was a great guy.
