This actually would work pretty well, if done religiously. Unless doing your own tips, it probably wouldn't work very well with busy cue repairmen. At any time, they have a bunch of tips to replace, and the chance of them leaving that small sliver of remaining leather from the previous tip...? Well, let's just say it's the chances of the Clintons staying together if Hillary loses. However, I agree with you, this does work, it does the function of a fiber base to protect either the ferrule or the OEM ferrule base.
On the fiber base ruining the hit of a cue, as opined above. If this was the case, most every cue built by George Balabushka and Gus Szamboti would have a ruined hit, as they used tips with fiber bases. Also, the cues today made by Barry Szamboti and Pete Tascarella would have a ruined hit with fiber bases, as that's how they make them. Anybody believe that? No, I don't think so.
As another erudite poster on this forum often states, you truly can't make this stuff up.
All the best,
