5 Hole Octave Tongue Switch

While working on making the change from 4 hole octaves to 5 hole octaves I found myself trying to tongue switch while holding a 5 hole octave. For instance switching between 4 and 8 on the V chord. I did this because part of my learning to switch to hole 1 involves going from 4 to 1 with the octave in-between. But the five hole embouchure is a bit trickier as switching involves tongue blocking 4 holes in the wider embouchure. Is this worth pursuing? Thanks!
