Can I Change This Fishes Specie With Paint?

I can't get kokanee replicas in the smaller sizes I want ( 12" to"14") but I can get brookie and rainbows. My question is; Do you think it would be noticeable if I used the trout replicas and painted them kokanee colors. I realize the bodies are slightly different, but would anyone notice?
What I am attempting for my first project is 4 kokanee for the wall. The largest being a spawning male followed by a spawning female and then with 2 bright fish. I will appreciate you guidance. Do you find it amazing how very little old men novices know? Thanks again, Steve

Incidentally it's my 75th birthday today and I am planning on spending the day carving and painting fish. 6 weeks ago all I could do is sit in my boat and occasionally catch one.

 

Great! It will be our secret.
Yesterday I finished my 2nd fish, a Kamloop trout. I've still got a tremendous amount to learn, but its coming along. I will start on my Kokanee project tomorrow. I am so delighted to having found this forum and all of its members that are willing to share their wealth of knowledge and experience. Truly awesome. With your help it makes an old man believe he can do anything.
These are my first two attempts. Hopefully I can do better. Much better!

 

Thanks for the feed-back. What I had in mind was a 20" male koke (spawner) reproduction from McKenzie (painted appropriately) and then use 3 smaller (maybe 14" to 16" rainbow/brook) painted appropriate Koke colors. I lack the skills to modify any reproductions and just thought (hoped) I could get away with using the rainbow or brook repros to complete the package. I, again, hoped that the spawning mail colored up would set the tone for the imagery.
The correct solution would be to find some Koke reproductions, but I've had no success finding Koke's under 20", Male or female.
If its not going to look true, I think I'll pass on my friends request and move on to something else. My old Grandpa always told me, "If its worth doing....Do it right" . Th hard part of those timely instructions is that I don't know is how to put this grouping together right. Thanks Again, Steve

 

Thanks, Do you have links for the blanks suppliers? You just put a big smile on an old mans face. I truly hope I can find what I need. Thanks again, Steve

Thank you for the birthday wish. I'm not sharp enough to think of just doing it and waiting for feed-back. I for sure (unless I forget) will remember that for similar quandaries I suffer through. Enjoy this beautiful fall day wherever you are. Steve

 

I found the links and sent out inquires as to availability.. Thanks. I was going to bring you a six pack of beer for the advice, but you live too far away from Utah so I'll just drink it and say thanks with each and every one. That's nice of me isn't it?
Quick question; Do you have any experience with these blanks?

 

It truly is great. I'm still awaiting responses. We are attempting a little carving, which might do, but our carvings lack the detail found on blanks. I'll post some pictures showing what I am attempting to do as this project develops.
In light of the fact that I don't know anything I'm a little reluctant to show my attempts until I realize that not one of you professionals was born an artist or a taxidermist Which are ultimately the same thing.
I am not going anywhere due to the pandemic and no one comes around so I need someone to gauge my attempts...... if I'm moving ahead or in full retreat. Thanks once again for your guidance. Steve Henline, Spanish Fork, Utah
