Yeah, the Keller shells I used were 5.4mm, and didn't do anything good with any type drumhead. I'd bet those shells you have would respond a lot better, and would suit square sizes.
That's another thing I didn't even think of. Nicko's kit was a heavy shelled sonor, something like 13mm. New shells like those I use would be less rigid.

Now THESE are deep shells:
