I bought a keyboard without the numpad about ten years ago and rarely miss it (I do have the arrows and keys above them). I would miss it with my work keyboard, but I don't miss it on my personal use gaming PC.
Just add a USB 10 key keyboard. Actually, it'd be neat if they made a keyboard with a detachable 10 key portion. Add a USB port so it can plug into the larger keyboard as an accessory.
There's the Everest line of keyboards by MOUNTAIN that does that, although they've recently had very massive sales (like 60-70% off type stuff) so idk if the company's doing alright.
