ESP8285 SPI vs HSPI

I am using a custom PCB for an academic project which uses Decawave DWM1000. I am planning to use ESP8285. I was looking at the datasheet for the same and was wondering if i can use the SPI instead of HSPI to interface the DWM1000.

20 SDIO_CMD I/O Connects to SD_CMD (Series R: 200Ω); SPI_CS0; GPIO11.
21SDIO_CLK I/O Connects to SD_CLK (Series R: 200Ω); SPI_CLK; GPIO6.
22 SDIO_DATA_0 I/O Connects to SD_D0 (Series R: 200Ω); SPI_MSIO; GPIO7.
23 SDIO_DATA_1 I/O Connects to SD_D1 (Series R: 200Ω); SPI_MOSI; GPIO8.


Has anyone done this before? Please suggest.
