You could do it via a recursive template but you'd have to keep re-calculating your grouping key which is quite expensive you can only get the benefit of using a key to speed things up if the key value can be expressed as a single xpath which it can't in your case. So unless you _really_ need it to be a single pass without any extension function (in which case ask again) I'd definitely do it in two passes, first collecting together the grouping key then either in asecond transformation or via node-set,do the grouping.
