Yes, the new Head racquet might be interesting (prototype for now. It seems very similar to the new Tecnifibre TF-X1.
Today Tecnifibre announced the Tecnifibre TF-X1, a new racquet in the comfort category and an interesting competitor to the Wilson Clash.

I got a cool box in the mail the other day. In it was a blacked-out racquet with the text "YOU GOT THIS". It's a new secret racquet from HEAD.

Both seem to have beams around 24mm which would make close to classical tweener (Pure Drive, Ezone 100) territory.
Last but not least, and without any scientific data , I would stay clear of any racquet that is 70 or more strung (approx 72-73 unstrung). I can already feel a slight difference in comfort between the Ezone 100 and Vcore 100 and they have 3 point difference in stiffness (71 vs 68 unstrung ).
Unfortunately, light racquets such as the Pure Drive and Ezone 100, need the high stiffness and thick beams, to offer power and stability. The best way of course from a purely arm comfort perspective, would be to use a heavier racquet with a more flexible layup. If you search this forum for arm friendly and tennis elbow posts, you can see thousands of comments about the subject.
And again, do indeed try some multifilament strings. String at 24-25 kg, or more if you hit very hard. Comfort is guaranteed to improve !
