Since a short beverage hasn't so much directivity, the first good 
option to take advantages is not to make it bidirectional.
The pattern improvement lengthening such antenna from 90m to 120m is 
surely noticeable on 160m, meanwhile the detriment on the highest band 
is quite questionable.
Giving up to the highest band (40m) where other type of antennas can 
also provide good results, a stack of beverages separated about 40m 
horizontally would make an antenna that performs excellent on 80 and 
that's much more effective on 160 than the single one.
