Send SPI instructions to several devices at once

I have múltiple sensors (all are the same one) and to accelerate data acquisition I'm thinking on send "measure" instruction to all of them at the same time, by selecting SS signal of all of them at the same time.

Is it feasible?? Is there any other solution?? Thanks in advance

As long as the MISO output of ALL of the Slaves are TriStated while the command is being send. If each sensor is trying to drive MISO, they will fight and the one with the stronger output Circuit will perhaps send data. all of the Slaves can/will damage each other.

If you put a 74HC125 TriState buffer between each of the SO pins and MISO and drove the '125s !OE pin with a different Arduino Pin, It could work.

Without additional hardware I would not do it.
