Is this hybrid rail made yet?

Mlok+Arca rail for chassis/ARs. Seems logical. I'm thinking more handguard style since they are popping up on bolt guns also. Would be a nice option.

Area419 and Sawtooth Rifles have a few options.

Yep, Area 419. Great products.

Not yet, but the Seekin sp3r rail would be a shoe in given it's shape.

We make a handful of adapters to go from an M-Lok forend (or buttstock if that's your jam ) to Arca. Anything from short, little guys at 3.3" up to 10.25"!
