Mag swaps on an SKS are cumbersome at best, even when modified to accept AK mags. Might be fun and look cool, but when carrying ammo on strippers, loading is faster and easier with the original box mag.
Playing with a gun that is in poor condition is not off the table for me, and I admit to doing a few mods from time to time. Most were necessitated by lack of parts availability, or otherwise unrepairable damage. Never found a reason to modify any surplus toy that was in good condition with matching numbers.
And if you are in Canada, isn't there a 5 round limit on magazine capacity?! This makes the modification even less practical, IMO.
Lets make an already heavy rifle weigh even more! Lets make it necessary to carry loaded magazines so movement is more restricted and requires more energy!
You are certainly free to do whatever is lawful to your toys. Just looks like Bubba had a hand in it, to me.
Dropping the mic, eh!
