merchant idea if possible?

[Trackye]

Would it be possible to make a merchant that his sell list is updated?

Something like You have X NPC ( merchant ) and every hour or so a script checks through the items in the DB and selects randomly say 10 or 20 items from the database that have a sell value and are not no drop then adds then to the merchant list setting the price to be something like price value of item normallyx10?

Would that be possible? Would kindof be like having 10 or so Bazaar vendors if it was possible.

Also is there a place where say premade custom merchants are posted that people can look through for their own local servers or something?
