Hot to select attributes based on aggregated weights?

I would like to make a selection of let's say top 10 attributes selected by using aggregation of more than one weighting operators and apply this selection to original example set.

Select by weight operator can use only weight input and there is no operator for weight aggregation.

I can only use weight to data and perform aggregation afterwards, then use sorting and filtering, but then is is impossible to use this data again as weights. (data to weights will always produce 1)

Is there any other way to achieve this selection?

Thanks, 

Nejc
