So glad you decided to join us. I would definitely follow the above link from @N F C to our Breed Discussion forums and ask there, there may be others that have crossed these breeds.
Welcome to BYC. I think you'll end up with a messy gold colored columbian. I've mixed all kinds of things but not those colors. I love the mixed breeds and colors, they are all so unique.
I have never bred those colors. I would normally refer you to the Kippen Jungle color genetics calculator but I don't see Lemon Cuckoo on the list. Maybe you can find it under another term, though.
Thanks for joining and welcome to BackYard Chickens!
