I like the way you think....
Sadly the mags would probably be "designed for pistol and rifle use" and therefore still pinned to 5.... But if there is a way to get "pistol use only" on them and have 10 rounders i may need to get me a new riffle.
Im sure some mfg somewhere could step up and build them. Its been done more than once and turns out to be a profitable enterprise so why not?
The handgun versions also need to be "commonly available" here in Canada to make the 10 rd pistol mags GTG. No doubt the RCMP would be the arbiters of what "commonly available" means.
