Actually, theoretically speaking, it can do that - as being transaction 
statefull and VIA being relevant at transaction level, openSIPS could 
strip all received VIA , store them into transaction and restore them in 
replies when sending out.
Actually, IMHO, VIA stack is pointless in transactions statefull proxies 
.....because a proxy keeps in transaction all information required to 
route back the replies...no need for VIA..

With some hacks in TM, you could do that, but it is a bit non-sense from 
RFC pov.
