I'm afraid you misunderstood me.

I don't have a problem with using vay' and then ghaH, as you suggested. It is what I would naturally do, in order to avoid hitting the -lu'/-laH problem.

The point of this thread, was to share my disappointment; on one hand we have a suffix, which we could use in order to refer to someone indefinite, but on the other hand, the -lu'/-laH rule, undermines our ability to use -lu' to its fullest, thus limiting its use to expressing passive voice.

Anyway, there are plenty of choices available, so all is good.
