since they signed agreements with WMZ and Ukash
Then why not have WMZ -> BTC?
or at least WMZ -> LR -> BTC
Maybe they would go for it. Webmoney is notorious in not allowing their e-currency to be exchanged with any other e-currencies. At least not directly. They seized all exchanger accounts that used to autoexchange WMZ->LR and other digital goldz.
WebMoney does not have an issue with exchanging to other e-currencies, however they do have an issue with AUTO exchanges as those are a prime target to launder stolen funds, funds from hacked accounts and such!
