No.
Besides the memories and emotional attachment I have to my current collection, replacing it would be effectively impossible.
When Ebay first appeared, there was all manner of excited dealing going on, but after the choice stuff found a home it flatlined. Silly prices for mostly junk. (Finding truly collectable collectables is still occasionally possible, but is time-consuming drudgery at best.)
Most of my stuff pre-dates that. It was largely cherry picked from collections that Barry Levin (the de facto "inventor" of estate pipes) bought from widows and so forth, before they were cleaned up and resold. Circumstances that can't be replicated today. Pipestud, Mike Glukler, Marty Pulvers and etc. are in a situation where they could do it to some degree, but the majority of the top quality pieces are no longer in circulation as a categorical thing. (Specific distribution instructions usually accompany such collections when their owner passes on or quits the hobby, which usually means a short list of friends. They rarely appear on the general buying public's radar.)
