Yes, that is just what FILL-IN WIDE1-1 digi's do. No matter
how may copies get to the central digi, it will only digipeat one.
And nothing is simpler than a WIDE1-1 digi. de Wb4APR, Bob

I wanted to state that what I'm trying to do is capture small
trackers better. This is no different than what a multi-receive
site repeater does. It has a "voter" that takes the best quieting
signal and transmits it. I want to do the same here, If I have 4
copies of the same packet each from 4 different participating
receivers and the packet is eligible for retransmission, only 1
copy gets sent out over RF. The central digi will still be CSMA
to the other traffic on channel. I want to use the internet as the
medium to bring the traffic to the central digi.
