For fixed-length formats (like 'd'), a '*' means "consume the remaining arguments". For formats that can have a length (like the ones you are trying to switch to), a '*' means "use the length of the next argument".

So you need to repeat the variable-length format specifications an appropriate number of times. Like: 

'l5Z*'.('Z*'x@s)
