You can try that. I managed to get about 1.9Mbps (simplex, so no ACKing etc) using shockburst on nrf52. So, you would need to have 6 transmitters and 6 receivers, configured on different channels.

Bluetooth is to slow that is for sure.

But using 4 or 5 antennas and a MIMO technology (the same used for wifi N) maybe one could build a fast enough rF transceiver.

Wifi consumes too much power for my needs.

BTLE has a fixed underlying data rate of 1Mb/s, with the actual rate you get after overhead lower than that, max would be around 800kb/s, so you'd need at least 14 separate simultaneous connections, more to account for packet loss which you would probably get with 14 transmitters and receivers in one place.

So basically, no, you can't do this with BTLE. You can't even do it with normal BT which runs around 2Mb/s after overhead. You need a different technology entirely, perhaps WiFi at 100Mb/s would work.
