Could you put a 1" wobble on the hextension?
i don't know why not. i have used them with at least a 1/2 dozen 3/8 ratchet brands and at least that many socket brands with no fitment issues. i see no reason a short wobble won't work. i have a short sk and may try but i have no doubt it would fit.
i have seen times when one brand of socket may not fit well on a ratchet. usually the drive end is too square and the socket isn't square enough and they are hard to get on an off. no issues with the hextension.
