That's exactly what I've decided to do; though I'm playing roughly 30 mins at a time as this central position is pretty tough to get used to on the fretting hand, I can feel a slight ache developing on the knuckle side of my fretting hand, I think it's due to leaving down every finger until it needs to move to a note.

It may be well worth the effort to abandon all your old tunes and exercises and really hone a strong, reliable technique. It won't take very long with a good teacher and one or two hours a day of focused, mindful practice at really slow tempos.
I'm now only appreciating this advice as it's been a learning curve over the past few days and I definitely need to work on my thumb. I can now keep it fairly relaxed as I concentrate going up and down the scale but it has a tendancy (when I'm holding the notes down till any given finger needs to move exercise) to sneak back toward a locked bottom knuckle position (like in photo). It's not so much the pressure than my thumb is used to doing it. Funnily enough as you say it's related to bringing my forearm into a better position that enables my thumb to somewhat straighten and unlock at base knuckle.

When I look at that top view, it appears from the position of your thumb that you are applying a lot of pressure to force your fingers to the strings. Do you find that the muscle at the base of your thumb feels tired?
Also, I can see from the picture that your elbow is pulled back and this leads to your palm being more below the edge of the fretboard rather than out in front. This might be part of the difficulty you experience when you try to do this exercise on the low E and keep from muting the A. If you brought your elbow forward, that would bring your forearm to be more in the same plane as the fretboard, and the back of your hand in the same plane as well.
