Full blank lineups don't work anymore. He will follow the depth chart for the SF-C positions with that setup. The coach may occasionally place a backup SF at SG some minutes if they are suited for it, but for the majority of the minutes, it should play out like a balanced minute attack between the 4-5 guards you have set up to be in the blanked spots.
There is no longer a complete blank lineup strategy that works well, like seasons ago.
