I don't see much benefit in this, since it's still missing regular layout even if we ignored NumLock.
It would be easier, healthier and more comfortable just use normal external keyboard with/without laptop stand.

The stand allows using the external keyboard in the same physical location / orientation as the one built in to the laptop (making it easier / healthier for someone with RSI instead of using a smaller laptop keyboard or creating strain because the external keyboard is in a different location / orientation to the "standard" keyboard)
