Would it be weird if I did this?

So I need some opinions on if this would be tacky or not. So my mother passed away last July from alzheimers and this year would have been 55 years married for her and my dad. For their anniversary, I was thinking of getting her wedding bouquet recreated with velvet flowers so they won’t die and having it sent to my dad from my mom. Not sure if that’s weird or not, but I was just thinking how if she could be here, she would’ve sent them, she just can’t so I’m arranging it for her. I was gonna have the card read “all my love from the beyond. Happy anniversary to my Danny boy! I will always be with you and I love you forever and for always. Love, Brenda” or something to that effect. I just wasn’t sure if it’s weird to do that or not.
