There is no market out there that lets you trade slower in return for providing a smaller margin for market makers.

It is possible to build one, but it would look so different from existing markets that it would be an uphill battle to get people to adopt it.

Not sure I follow exactly what you're proposing. But it sounds like this was IEX's approach with their self-imposed speed bump.

IEX's speed bump in the end simply allowed their special internal dpeg order type to pull slightly back when they saw adverse movements incoming, for many normal trades it's essentially an exchange that acts like it's a little farther away (longer latency) than it actually is with some dark order types which move weird.
