If you want buckling springs I would just get those and put up with the layout, as you say, nothing else is going to be exactly the same. I find alps and mx switches more predictable typing experience but lack the same feel and are just not as loud in the same way.
Blue or Amber Alps would be my pick if you can find a board in the layout you want that supports Alps. I strongly recommend trying them before you invest, whites used to be cheaper than blues, so if you might get lucky with preferring whites and save some cash.
Zeal Clickiez are probably the closest to what you are going to get out of MX that I have tried, although I had to spring swap to get the feel how I prefer. They are not cheap especially when you add in new springs.
You can always ball bearing mod the MX switches to add in some extra thocc.
