Do you want ortholinear or do you want to stick with staggered keys like the Microsoft Ergo Keyboard?
If you want to stick with traditional stagger but split, then Keeb.io has some options:
Sinc for 75% split
Quefrency for 60%/65% split
If you just want a Alice style keyboard with a number that is similar to your current keyboard, then Feker Alice 98 might be a better choice. Ergo keyboards rarely (if ever) come with numpads.
