Yes, I've seen it. It's quite neat. On the other hand it seems more complex to implement in hardware.
In the simplest possible design, the cost of vector support in the MRISC32 is essentially the cost of the register file (i.e. the register memory), since the vector control logic just consists of a few adders and flip-flops, and the scalar execution units can be reused for vector operations.
